What does all these FindBugs prefixes AM, BC, DP, ... mean?

Question

http://findbugs.sourceforge.net/bugDescriptions.html contains a long list of error types. They belong to a category like correctness and performance but do start with an prefix too. EQ for equality is obvious, same like SQL or BIT. But some cryptic. Is there a list what all these prefixes mean?

Answer 1

Some of them are explained in a PDF I found on Google: http://www.cs.colostate.edu/~mstrout/CS653Spring06/Slides/student-01-sandeep-findbugs.pdf (last page)

I hope it's OK to quote it here:

Code Description

• CN Cloneable Not Implemented Correctly
• DC Double Checked Locking
• DE Dropped Exception
• EC Suspicious Equals Comparison
• Eq Bad Covariant Definition of Equals
• HE Equal Objects Must Have Equal Hashcodes
• IS2 Inconsistent Synchronization
• MS Static Field Modifiable By Untrusted Code
• NP Null Pointer Dereference
• NS Non-Short-Circuit Boolean Operator
• OS Open Stream
• RCN Redundant Comparison to Null
• RR Read Return Should Be Checked
• RV Return Value Should Be Checked
• Se Non-serializable Serializable Class
• UR Uninitialized Read In Constructor
• UW Unconditional Wait
• Wa Wait Not In Loop

Answer 2

There is a single XML file within the FindBugs codebase that lists all the alerts that can be generated. You can view this file at the Google code project here.

Here is an excerpt from the file:

<BugPattern abbrev="NP" type="NP_GUARANTEED_DEREF" category="CORRECTNESS"/>
<BugPattern abbrev="NP" type="NP_GUARANTEED_DEREF_ON_EXCEPTION_PATH" category="CORRECTNESS"/>
<BugPattern abbrev="OS" type="OS_OPEN_STREAM" category="BAD_PRACTICE" />
<BugPattern abbrev="OS" type="OS_OPEN_STREAM_EXCEPTION_PATH" category="BAD_PRACTICE" />
<BugPattern abbrev="PZLA" type="PZLA_PREFER_ZERO_LENGTH_ARRAYS" category="STYLE" />

The detailed descriptions are stored in a different file, which you can browse here.
