clonevm on
The new clonevm attribute on the <java> task looked like exactly what I
needed, but it seems to only clone the built in system properties and not
ones specified one the commandline (e.g. ant -Dmyapp.foo=bar). I tried
changing BuiltinPropertySetName to "all" didn't work.
How can this be done?
Thanks,

it really irritates me that you cannot clone jvms 100% foolproofly, we
really need a proper implementation of fork() into the java runtime. At
least ant can extract env variables without waiting for java1.5, that
being part of the exec() payload, but we cannot do things like system
process priority and other advanced options. and of course file handles,
but that is a side problem.
FYI, although win32 doesnt have a fork() call, it is in the kernel -the
(never used) posix subsystem makes the call, so it has to be there.

are Ant properties, not system properties.
I introduced clonevm for Gump initially that sets things like
java.awt.headless and needs to pass this to forked unit tests and so
on.
