I've never seen this at all.
Most likely the "runnable" that is stuck on the executor, or the executor
itself, is not recording the thead context classloader or similar. Do you
have control over the creation of that runnable? (I've never looked at the
procrun stuff) If so, could you grab the context classloader at runnable
creation time (on the original thread) and then in the first line of the run
method set the context classloader to it on that background thread? I'm not
really sure if that will help, but it might. Alternatively, in the run
method, try calling Thread.currentThread().setContextClassloader(null) to
force it null to try using the system classpath. The spi.FactoryFinder stuff
pretty much all use the context classloader so if that isn't "correct", it
might cause a problem.
