HookConfigurator in RCP under JDK 6 [message #480831]

In the RCP app I'm working on, I've implemented the HookConfigurator and
ClassLoadingHook to include a few external jar files onto the classpath.
These jars (scripting engine related) are added post install and so
can't be pre-wrapped in a bundle. They are typically things like
groovy and groovy-engine jars pairs, or other script engines.

Under JDK 5, things work well. I can drop new scripting engine related
jars into the external directory and they get picked up for use by the RCP.
Under JDK 6, the RCP fails to find the new script engine
i.e classes from that jar.

Has anyone run into something similar?
What am I doing wrong?

Its hard to tell. Can you debug the class loader to make sure the
bundle class loader is searching the jars you added? If possible could
you put together a testcase to reproduce. If so I would open a bug
against Equinox->Framework at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Equinox
