I tried what you suggested and yes the IRuntime class is loaded without any
issues.
I added the following right at the beginning of the Activator.start() method:
// Experiment to see if this bundle has access to IRuntime class
log.info("start: loading IRuntime class...");
Class iRuntimeClass =
context.getBundle().loadClass("com.raritan.polaris.plugins.dynamic.bridge.IRuntime");
log.info("start: IRuntime class loaded, name= " + iRuntimeClass.getName());
The resulting output:
2013-03-28 21:25:08,314 INFO [Start Level Event Dispatcher] Activator: start:
loading IRuntime class...
2013-03-28 21:25:08,314 INFO [Start Level Event Dispatcher] Activator: start:
IRuntime class loaded, name= com.raritan.polaris.plugins.dynamic.bridge.IRuntime
