Description Kevin Barnes

Launching any build.xml causes a memory leak on windows vista. Longer running build files seem to leak more than <echo>Hello World</echo>. I haven't been able to reproduce the leak on XP or OS X, and I haven't been able to reproduce it by launching standard java apps.
I've been building the SWT libraries a lot today and have suffered one OutOfMemoryError

What type of Out of memory: heap or permGen?
Which JVM are you using

Comment 2 Kevin Barnes

perm gen. Sun 1.5.0_10.
I'll update this PR once I have more info from a profiler.

Note that I have yet to find a profiler that reliably will show me permgen leaks.

Any work planned on this for 3.3?

I plan on looking at this some more, but so far I haven't found anything interesting. It also does not appear to be a major issue as I have run a lot of build files, but haven't seen any OOM's since I filed this bug.

I'm not seeing this leak anymore. I ran a bunch of builds with a profiler attached and memory usage does not grow.
