FindBugs™ - Find Bugs in Java Programs
This is the web page for FindBugs, a program which looks for bugs in Java code. It is free software, distributed under the terms of the Lesser GNU Public License.
The name FindBugs™ and the Findbugs logo are trademarked by The University of Maryland.
FindBugs requires JRE (or JDK) 1.4.0 or later to run. However, it can analyze programs compiled for any version of Java.
The current version of FindBugs is 0.9.4, released on November 30, 2005.
FindBugs is beta quality software. You may find bugs in it, and the features and source code may change significantly in future releases. We are very interested in getting feedback on how to improve FindBugs. Send your comments to daveho@users.sourceforge.net.
