Re: -J option task question

Since I haven't heard anything further, let me rephrase the question. Is 
there anything I need to do (outside of the invocation of the task, for 
example) in order to ensure that fork works in the javac task?

If you set 'fork=true' (or 'yes' or 'on') then <javac> will be executed
in a separate VM. 

If you run ant with '-debug' you will see the exact command line being
used to invoke the forked VM.
