<p> This cast will always throw a ClassCastException. FindBugs tracks type information from instanceof checks, and also uses more precise information about the types of values returned from methods and loaded from fields. Thus, it may have more precise information that just the declared type of a variable, and can use this to determine that a cast will always throw an exception at runtime. </p>

Uninitialized read of field in constructor

<p> This constructor reads a field which has not yet been assigned a value.&nbsp; This is often caused when the programmer mistakenly uses the field instead of one of the constructor's parameters.</p>

Double assignment of local variable

<p> This method contains a double assignment of a local variable; e.g. </p> <pre> public void foo() { int x,y; x = x = 17; } </pre> <p>Assigning the same value to a variable twice is useless, and may indicate a logic error or typo.</p>

Return value of method without side effect is ignored

<p>This code calls a method and ignores the return value. However our analysis shows that the method (including its implementations in subclasses if any) does not produce any effect other than return value. Thus this call can be removed. </p> <p>We are trying to reduce the false positives as much as possible, but in some cases this warning might be wrong. Common false-positive cases include:</p> <p>- The method is designed to be overridden and produce a side effect in other projects which are out of the scope of the analysis.</p> <p>- The method is called to trigger the class loading which may have a side effect.</p> <p>- The method is called just to get some exception.</p> <p>If you feel that our assumption is incorrect, you can use a @CheckReturnValue annotation to instruct FindBugs that ignoring the return value of this method is acceptable. </p>

Null pointer dereference

<p> A null pointer is dereferenced here.&nbsp; This will lead to a <code>NullPointerException</code> when the code is executed.</p>

equals() used to compare array and nonarray

<p> This method invokes the .equals(Object o) to compare an array and a reference that doesn't seem to be an array. If things being compared are of different types, they are guaranteed to be unequal and the comparison is almost certainly an error. Even if they are both arrays, the equals method on arrays only determines of the two arrays are the same object. To compare the contents of the arrays, use java.util.Arrays.equals(Object[], Object[]). </p>

Useless non-empty void method

<p>Our analysis shows that this non-empty void method does not actually perform any useful work. Please check it: probably there's a mistake in its code or its body can be fully removed. </p> <p>We are trying to reduce the false positives as much as possible, but in some cases this warning might be wrong. Common false-positive cases include:</p> <p>- The method is intended to trigger loading of some class which may have a side effect.</p> <p>- The method is intended to implicitly throw some obscure exception.</p>

Nullcheck of value previously dereferenced

<p> A value is checked here to see whether it is null, but this value can't be null because it was previously dereferenced and if it were null a null pointer exception would have occurred at the earlier dereference. Essentially, this code and the previous dereference disagree as to whether this value is allowed to be null. Either the check is redundant or the previous dereference is erroneous.</p>

Method discards result of readLine after checking if it is non-null

<p> The value returned by readLine is discarded after checking to see if the return value is non-null. In almost all situations, if the result is non-null, you will want to use that non-null value. Calling readLine again will give you a different line.</p>

Unused field

<p> This field is never used.&nbsp; Consider removing it from the class.</p>

No relationship between generic parameter and method argument

<p> This call to a generic collection method contains an argument with an incompatible class from that of the collection's parameter (i.e., the type of the argument is neither a supertype nor a subtype of the corresponding generic type argument). Therefore, it is unlikely that the collection contains any objects that are equal to the method argument used here. Most likely, the wrong value is being passed to the method.</p> <p>In general, instances of two unrelated classes are not equal. For example, if the <code>Foo</code> and <code>Bar</code> classes are not related by subtyping, then an instance of <code>Foo</code> should not be equal to an instance of <code>Bar</code>. Among other issues, doing so will likely result in an equals method that is not symmetrical. For example, if you define the <code>Foo</code> class so that a <code>Foo</code> can be equal to a <code>String</code>, your equals method isn't symmetrical since a <code>String</code> can only be equal to a <code>String</code>. </p> <p>In rare cases, people do define nonsymmetrical equals methods and still manage to make their code work. Although none of the APIs document or guarantee it, it is typically the case that if you check if a <code>Collection&lt;String&gt;</code> contains a <code>Foo</code>, the equals method of argument (e.g., the equals method of the <code>Foo</code> class) used to perform the equality checks. </p>

Doomed attempt to append to an object output stream

<p> This code opens a file in append mode and then wraps the result in an object output stream. This won't allow you to append to an existing object output stream stored in a file. If you want to be able to append to an object output stream, you need to keep the object output stream open. </p> <p>The only situation in which opening a file in append mode and the writing an object output stream could work is if on reading the file you plan to open it in random access mode and seek to the byte offset where the append started. </p> <p> TODO: example. </p>

Clone method may return null

<p> This clone method seems to return null in some circumstances, but clone is never allowed to return a null value. If you are convinced this path is unreachable, throw an AssertionError instead. </p>

Bad comparison of signed byte

<p> Signed bytes can only have a value in the range -128 to 127. Comparing a signed byte with a value outside that range is vacuous and likely to be incorrect. To convert a signed byte <code>b</code> to an unsigned value in the range 0..255, use <code>0xff &amp; b</code> </p>

Unread field

<p> This field is never read.&nbsp; Consider removing it from the class.</p>

Useless control flow

<p> This method contains a useless control flow statement, where control flow continues onto the same place regardless of whether or not the branch is taken. For example, this is caused by having an empty statement block for an <code>if</code> statement:</p> <pre> if (argv.length == 0) { // TODO: handle this case } </pre>

equals() method does not check for null argument

<p> This implementation of equals(Object) violates the contract defined by java.lang.Object.equals() because it does not check for null being passed as the argument. All equals() methods should return false if passed a null value. </p>

Method call passes null for non-null parameter

<p> This method call passes a null value for a non-null method parameter. Either the parameter is annotated as a parameter that should always be non-null, or analysis has shown that it will always be dereferenced. </p>

Possible null pointer dereference

<p> There is a branch of statement that, <em>if executed,</em> guarantees that a null value will be dereferenced, which would generate a <code>NullPointerException</code> when the code is executed. Of course, the problem might be that the branch or statement is infeasible and that the null pointer exception can't ever be executed; deciding that is beyond the ability of FindBugs. </p>

Should be a static inner class

<p> This class is an inner class, but does not use its embedded reference to the object which created it.&nbsp; This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.&nbsp; If possible, the class should be made static. </p>

Dead store to local variable

<p> This instruction assigns a value to a local variable, but the value is not read or used in any subsequent instruction. Often, this indicates an error, because the value computed is never used. </p> <p> Note that Sun's javac compiler often generates dead stores for final local variables. Because FindBugs is a bytecode-based tool, there is no easy way to eliminate these false positives. </p>

Invocation of toString on an unnamed array

<p> The code invokes toString on an (anonymous) array. Calling toString on an array generates a fairly useless result such as [C@16f0472. Consider using Arrays.toString to convert the array into a readable String that gives the contents of the array. See Programming Puzzlers, chapter 3, puzzle 12. </p>

equals(...) used to compare incompatible arrays

<p> This method invokes the .equals(Object o) to compare two arrays, but the arrays of of incompatible types (e.g., String[] and StringBuffer[], or String[] and int[]). They will never be equal. In addition, when equals(...) is used to compare arrays it only checks to see if they are the same array, and ignores the contents of the arrays. </p>

Class defines equals() and uses Object.hashCode()

<p> This class overrides <code>equals(Object)</code>, but does not override <code>hashCode()</code>, and inherits the implementation of <code>hashCode()</code> from <code>java.lang.Object</code> (which returns the identity hash code, an arbitrary value assigned to the object by the VM).&nbsp; Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes.</p> <p>If you don't think instances of this class will ever be inserted into a HashMap/HashTable, the recommended <code>hashCode</code> implementation to use is:</p> <pre>public int hashCode() { assert false : "hashCode not designed"; return 42; // any arbitrary constant will do }</pre>

Double assignment of field

<p> This method contains a double assignment of a field; e.g. </p> <pre> int x,y; public void foo() { x = x = 17; } </pre> <p>Assigning to a field twice is useless, and may indicate a logic error or typo.</p>

Useless control flow to next line

<p> This method contains a useless control flow statement in which control flow follows to the same or following line regardless of whether or not the branch is taken. Often, this is caused by inadvertently using an empty statement as the body of an <code>if</code> statement, e.g.:</p> <pre> if (argv.length == 1); System.out.println("Hello, " + argv[0]); </pre>

Invocation of toString on an array

<p> The code invokes toString on an array, which will generate a fairly useless result such as [C@16f0472. Consider using Arrays.toString to convert the array into a readable String that gives the contents of the array. See Programming Puzzlers, chapter 3, puzzle 12. </p>

Code contains a hard coded reference to an absolute pathname

<p>This code constructs a File object using a hard coded to an absolute pathname (e.g., <code>new File("/home/dannyc/workspace/j2ee/src/share/com/sun/enterprise/deployment");</code> </p>

Method call passes null to a non-null parameter

<p> This method passes a null value as the parameter of a method which must be non-null. Either this parameter has been explicitly marked as @Nonnull, or analysis has determined that this parameter is always dereferenced. </p>

Possible null pointer dereference due to return value of called method

<p> The return value from a method is dereferenced without a null check, and the return value of that method is one that should generally be checked for null. This may lead to a <code>NullPointerException</code> when the code is executed. </p>

Reliance on default encoding

<p> Found a call to a method which will perform a byte to String (or String to byte) conversion, and will assume that the default platform encoding is suitable. This will cause the application behaviour to vary between platforms. Use an alternative API and specify a charset name or Charset object explicitly. </p>

Unusual equals method

<p> This class doesn't do any of the patterns we recognize for checking that the type of the argument is compatible with the type of the <code>this</code> object. There might not be anything wrong with this code, but it is worth reviewing. </p>

Static Thread.interrupted() method invoked on thread instance

<p> This method invokes the Thread.interrupted() method on a Thread object that appears to be a Thread object that is not the current thread. As the interrupted() method is static, the interrupted method will be called on a different object than the one the author intended. </p>

Self assignment of field

<p> This method contains a self assignment of a field; e.g. </p> <pre> int x; public void foo() { x = x; } </pre> <p>Such assignments are useless, and may indicate a logic error or typo.</p>

"." or "|" used for regular expression

<p> A String function is being invoked and "." or "|" is being passed to a parameter that takes a regular expression as an argument. Is this what you intended? For example <li>s.replaceAll(".", "/") will return a String in which <em>every</em> character has been replaced by a '/' character <li>s.split(".") <em>always</em> returns a zero length array of String <li>"ab|cd".replaceAll("|", "/") will return "/a/b/|/c/d/" <li>"ab|cd".split("|") will return array with six (!) elements: [, a, b, |, c, d] </p>

Use of class without a hashCode() method in a hashed data structure

<p> A class defines an equals(Object) method but not a hashCode() method, and thus doesn't fulfill the requirement that equal objects have equal hashCodes. An instance of this class is used in a hash data structure, making the need to fix this problem of highest importance.

Invocation of equals() on an array, which is equivalent to ==

<p> This method invokes the .equals(Object o) method on an array. Since arrays do not override the equals method of Object, calling equals on an array is the same as comparing their addresses. To compare the contents of the arrays, use <code>java.util.Arrays.equals(Object[], Object[])</code>. To compare the addresses of the arrays, it would be less confusing to explicitly check pointer equality using <code>==</code>. </p>

Overwritten increment

<p> The code performs an increment operation (e.g., <code>i++</code>) and then immediately overwrites it. For example, <code>i = i++</code> immediately overwrites the incremented value with the original value. </p>

clone method does not call super.clone()

<p> This non-final class defines a clone() method that does not call super.clone(). If this class ("<i>A</i>") is extended by a subclass ("<i>B</i>"), and the subclass <i>B</i> calls super.clone(), then it is likely that <i>B</i>'s clone() method will return an object of type <i>A</i>, which violates the standard contract for clone().</p> <p> If all clone() methods call super.clone(), then they are guaranteed to use Object.clone(), which always returns an object of the correct type.</p>

Finalizer does nothing but call superclass finalizer

<p> The only thing this <code>finalize()</code> method does is call the superclass's <code>finalize()</code> method, making it redundant.&nbsp; Delete it.</p>

Class inherits equals() and uses Object.hashCode()

<p> This class inherits <code>equals(Object)</code> from an abstract superclass, and <code>hashCode()</code> from <code>java.lang.Object</code> (which returns the identity hash code, an arbitrary value assigned to the object by the VM).&nbsp; Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes.</p> <p>If you don't want to define a hashCode method, and/or don't believe the object will ever be put into a HashMap/Hashtable, define the <code>hashCode()</code> method to throw <code>UnsupportedOperationException</code>.</p>

Self assignment of local variable

<p> This method contains a self assignment of a local variable; e.g.</p> <pre> public void foo() { int x = 3; x = x; } </pre> <p> Such assignments are useless, and may indicate a logic error or typo. </p>
