Steve Loughran commented on HADOOP-4721:
----------------------------------------
I dont think there is a memory leak, I just fear that too much is being
buffered -even on console output- though it could be hidden by Ant playing
games underneath. If Ant is still buffering everything going to stdout and
log4j is pushing to stdout, Ant could be the cause even though it is not in the
stack trace.
I will downgrade logging level to INFO and see if that is enough to make the
problem go away.
