How about posting the error?
If I remember right, which I might not be, the earlier suggestion was  
to the ant doc runtime options environment variables.
Again, posting the error might make for better guesses. But if the  
error is actually javac running out of memory looking at the ant doc  
for that...
http://ant.apache.org/manual/CoreTasks/javac.html
might be more help.

I was thinking fork it off as a separate process might help and  
checked if the ant javac task supports that, it does.

This might get you more memory as a separate process.
Then I also noticed...

Which appear to go with fork for the purpose you want.

I suppose here I might mention...
http://www.geocities.com/mik3hall/javasrc.html#antdoc

An XSLT transform for ant build files to HTML that I wrote a while  
back when I was learning some of the XML related stuff. Acutally, I'm  
looking at XML stuff again now, I should probably see if I can  
improve on this while I'm at it. One thing it does is insert links to  
the ant task documentation for the tasks included in the build  
targets. You have to add the xml-stylesheet processing instruction  
shown to the ant file, build.xml or whatever. Then just open the  
build file in a XSLT handling browser like Safari and find the  
compile target and click on javac to go to the doc.

Or Google around for that, someone's probably done a better one than  
my learning effort.
