Re: [weld-dev] Thread deadlock with osgi refresh

Hi all I use pax-cdi 1.0.0.RC2 with weld-osgi-bundle 2.3.5. And I have two bundles: bundleA and bundleB. BundleB has CDI beans and CDI container is created for bundleB. Besides bundleB depends on bundleA. Now I update bundleA and do osgi refresh using this code |Bundle systemBundle = bundleContext.getBundle(0); FrameworkWiring frameworkWiring = systemBundle.adapt(FrameworkWiring.class); frameworkWiring.refreshBundles(null); What I see in log of bundle B. |2017-05-08 12:31:42,831 | DEBUG | xFrameworkWiring | ? | BundleEvent STOPPING - com.bundleB 2017-05-08 12:31:42,832 | DEBUG | xFrameworkWiring | ? | ServiceEvent UNREGISTERING - [java.lang.Object] - com.bundleB 2017-05-08 12:31:42,832 | DEBUG | xFrameworkWiring | ? | BundleEvent STOPPED - com.bundleB 2017-05-08 12:31:42,845 | DEBUG | xFrameworkWiring | ? | BundleEvent UNRESOLVED - com.bundleB 2017-05-08 12:31:42,885 | DEBUG | xFrameworkWiring | ? | BundleEvent RESOLVED - com.bundleB 2017-05-08 12:31:42,886 | DEBUG | xFrameworkWiring | ? | BundleEvent STARTING - com.bundleB 2017-05-08 12:31:43,164 | DEBUG | xFrameworkWiring | ? | ServiceEvent REGISTERED - [java.lang.Object] - com.bundleB | Please,note that bundleB didn't change state to STARTED. When I don't use in bundleB CDI beans and CDI container is not created for bundleB then everything is ok - after bundleA update and osgi refresh bundleB reaches STARTED state. Is this a bug of weld or something else?
