OK, you mean that's the individual service's config file; it's
not in the ServiceStarter's config file?  In which case, it should
never be fetched by ServiceStarter, only by your service once it's
running.

What kind of ServiceDescriptor are you using?  If it's a
NonActivatableServiceDescriptor, then your service will be in
its own class loader with its own security context.

Yes, but the config file passed on the command line should not be the
one you showed above, it should be one specifically for ServiceStarter.

ServiceStarter.main does set a security manager if one isn't already set.

It's not clear to me why you're trying to reference them within
ServiceStarter's configuration.

The stack trace you supplied seems to indicate that the exception is
occurring when the ServiceStarter attempts to get its "serviceDescriptors"
configuration entry.  The config file you provided doesn't match that
scenario, however.  So, something's getting lost in your approximate
translation.  More precision is required to sort it out.
