Thread dead lock with osgi refresh

    Description

      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 12:31:43,164 | 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.
