Rohini Palaniswamy commented on PIG-3517:
-----------------------------------------
Does ANT_OPTS="-XX:MaxPermSize=xxx" work with forked junit tests? I was running
builds using -DdebugArgs="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=128M".
It is good to have this fixed by default without having to specify manually.
Not sure what the behaviour is when there are two jvmarg lines.
http://ant.apache.org/manual/using.html#arg says either of value or line but
not both. If that is the case, can we do <jvmarg
line="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=128M ${debugArgs}"/> ?
