SpotBugs is a program to find bugs in Java programs. It looks for instances of “bug patterns” — code instances that are likely to be errors.

This document describes version 3.1.1 of SpotBugs. We are very interested in getting your feedback on SpotBugs. Please visit the SpotBugs web page for the latest information on SpotBugs, contact information, and support resources such as information about the SpotBugs GitHub organization.
