FindBugs OutOfMemoryError
-------------------------

                 Key: MAPREDUCE-2906
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2906
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.22.0
         Environment: FindBugs 1.3.9, ant 1.8.2, RHEL6, Jenkins 1.414 in Tomcat 7.0.14, Sun
Java HotSpot(TM) 64-Bit Server VM
            Reporter: Joep Rottinghuis
            Assignee: Joep Rottinghuis


When running the findbugs target from Jenkins, I get an OutOfMemory error.
The "effort" in FindBugs is set to Max which ends up using a lot of memory to go through all
the classes. The jvmargs passed to FindBugs is hardcoded to 512 MB max.

We can leave the default to 512M, as long as we pass this as an ant parameter which can be
overwritten in individual cases through -D, or in the build.properties file (either basedir,
or user's home directory).
