Subject RE: ant.system.gc()?
Date Tue, 05 Nov 2002 21:31:02 GMT
I'm using 1.5.1, and my build was running out of memory without any javac invocations.  All
together, it would have made about 75 Ant and/or AntCall invocations.  I had to break it up
and call it from a batch file to avoid the memory problems.  Not a pleasing solution by any
means.

This is more likely a memory leak than anything else.

-use java1.4 or fork javac (it leaked in 1.3)
-use ant1.5.1 that fixes leaks related to <ant>
