Very true. Thanks for the reminder.

That's an excellent suggestion. I went ahead and
triggered a JVM thread dump on the hanging Ant
process. I have copied and pasted the thread dump at
the end of this e-mail message.

I've already tried this, as I've already indicated in
my previous e-mail. It works perfectly from the
command line.

Thanks for the suggestion. I tried this. It works from
the <exec>.

No need to remind a programmer. Google is the first
place that I consult even before posting to the
mailing list. It is much easier to search google than
it is to compose a detailed message explaining a
problem, then posting it to the mailing list.
Thanks for the suggestions,

P.S. I ran the my ant script in verbose mode, and then
I triggered a thread dump. Here is the output:
