PMD is a Java source code analyzer. It finds
unused variables, empty catch blocks, unnecessary
object creation, and more. It includes CPD, a tool to detect chunks of identical code.

This release includes eight new rules, a slew of bugfixes, and better support for JDK 1.5. Several rules were optimized; for example, UnusedModifer now runs about ten times faster.
PMD now has support for parsing JDK 1.5 source
code, including enumerations, generics,
annotations, and variable length arguments. There
are also 17 new rules, and several of the existing
rules have been optimized.
This release fixes bugs in the "sunsecure", "optimization", and "strictexception" rulesets; many exceptions were being thrown. If you downloaded 2.2, please try this instead.
There are several new rules (LocalVariableCouldBeFinal, MethodArgumentCouldBeFinal, AvoidInstantiatingObjectsInLoops, ArrayIsStoredDirectly, MethodReturnsInternalArray, AssignmentToNonFinalStatic, and AvoidConcatenatingNonLiteralsInStringBuffer), a few bugfixes, and a few new features. CPD supports any language, the symbol table code is much cleaner, the "run PMD" scripts are now in the "bin/" directory vs the "etc/" directory, and the rule overriding works better.
Many bugfixes and two new rules: AvoidProtectedFieldInFinalClass and SystemPrintln. Rules now have more consistent names, JDK 1.5 support is slightly better (although generics and annotations don't work yet), and CPD now has support for ignoring identifiers.
