FindBugs PLug-in
FindBugs is a program to find bugs in Java programs. It looks for instances of "bug patterns" - code instances that are likely to be errors.
FindBugs is made up of two major parts, the FindBugs engine and the FindBugs front-end. Currently, there are three different front-ends:
- a stand-alone (Swing-based) Java application
- an ANT task
- an Eclipse Plug-in
