PMD
Static code analyzer that uses sets of rules to identify problems within the software.
It detects things like duplicate code, dead code (unused variables, parameters or methods), method complexity (unnecessary ifs, etc.). It works mainly with the Java language, although, with less support, it also has rule sets for JavaScript, xsl and ecmascript.
