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).
