Re: [equinox-dev] Bundle with Extension can be invoked in RESOLVED state

What is the reason for this behaviour? I can workaround my problem by extending my extension point interface and making the extensions evaluate the Bundle.getState() to check if the bundle is active. But to me this behaviour seems somewhat unintuitive, and I would have thought that this is taken care of by the framework.

Best Regards,

André

Yes. I think you can still access the Bundle and its classes but can not access the BundleContext or interact with the OSGi framework, if the Bundle is not in the ACTIVE state.

Subject: [equinox-dev] Bundle with Extension can be invoked in RESOLVED state


Hi,

I hope I have not totally missed the point, but I have a bundle, let's call it B, that contains an extension for an extension point defined in bundle A. When I invoke a servlet in bundle A the extensions for the extension point are read out and the extension implementations are instantiated. A method getName() is called on the instances to provide a list of the available extensions. This works fine. However if in the osgi console I enter "stop B" and invoke my servlet in bundle A, it still can (and does) access the extension implementation in B. I have verified the state of B by typing "ss" in the osgi console and I'm told its in the RESOLVED state. I can make my scenario work by executing "uninstall B", but am surprised that stop is not enought. I read the javadoc about what RESOLVED means, but somehow this did not IMO clearly state if a bundle in RESOLVED state can be accessed.
Should a bundle that has been stopped still be accessible?
