Hrm. As long as the bundle who's activator you show here has access to
com.raritan.polaris.plugins.dynamic.bridge.IRuntime (and any classes it
references, remember) I'd expect it to work. If you throw
context.getBundle().loadClass("com.raritan.polaris.plugins.dynamic.bridge.IRuntime");
in there before creating the scripting container, does it successfully
resolve?
I'll work on running my sample in your version of equinox to see if an
incompatibility in the OSGiScriptingContainer. That would surprise me a
little bit, but it's worth investigating.
