Subject Re: Garbage collection question
Date Wed, 06 Apr 2005 02:02:57 GMT
Garbage collection is non-deterministic - the JVM gets to decide when to 
run it.  My guess would be that ANT has a reference to ALL the files and 
doesn't let go of any of them until all the tasks have run.  You can 
probably get around this with a little re-coding; I could be wrong, but 
I think Ant-Call (and its variants) might cause the task objects to be 
derefernced for every loop, meaning a little more CPU time, but 
hopefully no oyt-of-memory errors.  You might also look at either the 
ANT scriping task, or the Ant-contrib (from sourceforge) for-each tag.
