also, with no luck.  Any help or suggestions would be great, i'm a complete novice and have
been stuck at this for two days now - colleagues have been no help either!

It's been a long time, but I believe what we did was to use separate
VMs for CC and the builds themselves, i.e. use the Batch Builder
instead of the Ant Builder, that way you can have both running on
separate JDKs completely. Maybe now the Ant builder has a fork mode,
it's been years since I used CC. With the batch builder, you write a
DOS or SHELL (or PERL, PYTHON, etc...) script that sets everything up
correctly for the build, and then start Ant. The return code of the
Ant VM must be propagated correctly, but CC looks into the XML log
files as well if I recall correctly. Not quite what you are asking
for, but it's an alternative from what you are trying to do. Good
luck, --DD
