57<h1>Reporting Bugs in FindBugs</h1>
58
59<p>
60First of all, if you find a bug in FindBugs, and have the
61skills to fix it, we encourage you to unleash the power of open source and
62<a href="contributing.html">send us a patch</a>.&nbsp; We will gladly
63credit you on our website and in the manual.
64</p>
65
66<p>
67Please report bugs using the
68<a href="http://sourceforge.net/tracker/?atid=614693&group_id=96405&func=browse">Sourceforge
69bugs tracker</a>.&nbsp; Note that you need to be logged in to sourceforge to
70use the bug tracker.
71</p>
72
73<p>
74If you cannot use the Sourceforge tracker, you can try sending
75email to the <a href="http://www.cs.umd.edu/mailman/listinfo/findbugs-discuss"
76>findbugs-discuss mailing list</a>.&nbsp; You must be subscribed
77to the list to post a message.
78</p>
79
80<p>
81Finally, as a last resort, you can email <a href="mailto:findbugs@cs.umd.edu">findbugs@cs.umd.edu</a>.&nbsp;
82However, such emails are much less likely to be handled in a timely manner than
83posts to the tracker or mailing list.
84</p>
85
86<h2>False and Inaccurate Warnings</h2>
87
88<p>
89	Like most bug-detection tools based on static analysis, FindBugs
90	issues some warnings that do not correspond to real bugs.&nbsp;
91	While in general we would like to make the percentage of such warnings
92	small, we can never fully eliminate them.
93</p>
94
95<h2>Information to include</h2>
96
97<p>
98When reporting a bug, please include the following information:
99</p>
100<ul>
101<li>Complete list of steps to reproduce the problem</li>
102<li>If the error occurs during analysis, a jar file, class file,
103    or self-contained Java class that demonstrates the problem</li>
104<li>FindBugs version</li>
105<li>JDK/JRE version</li>
106<li>Host operating system</li>
107<li>Any exception traces, Eclipse error log entries, etc. that might
108    be relevant</li>
109</ul>
