> 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).
