Hi Yeah unfortunately class loading in OSGi and using 3rd party libraries that are NOT osgi friendly is a challenge, and you can hit these kind of issues here.
I am not sure if quartz offer an api where you can provide a custom classloader, so we can better control this when the store want's to load a class.
