Getting java.util.concurrent.CancellationException while stopping bundle in Fuse Fabric

XMLWordPrintable

      Steps to reproduce:
      1. Build the three provided bundles
      2. Create Fabric
      3. Import Profile "test-solution"
      4. container-add-profile root test-solution
      5. In your development environment, increment the version of "essentialCamelRoutesTest" to 1.0.1-SNAPSHOT and modify the profile to refer to this version.
      6. Rebuild all bundles
      7. Import profile again
      8. profile-refresh test-solution (right after the profile import)
      After approx. one minute you should get the first CancellationException, followed by one more every minute, for every bundle that has been loaded by the profile. At the end you get org.osgi.service.blueprint.container.ServiceUnavailableException: Timeout expired when waiting for mandatory OSGi service reference: (objectClass=org.apache.camel.spi.IdempotentRepository) and after this the profile is finally being refreshed correctly. During the wait and timeout the Fuse server seems to partially freeze and cannot even be shut down in a clean way.

      When we tried to stop bundles we were getting a cancellationException, concerning an OSGi service with the Interface "org.apache.camel.spi.IdempotentRepository". The container-status remained "installing" and after 5 minutes, the second exception "org.osgi.service.blueprint.container.ServiceUnavailableException" was thrown:
