    Refreshing highly dependent bundles crashes Felix but not Equinox

    Dustin S. Newbie

      Hi,

       

      Whenever a highly dependent bundle is refreshed (e.g. after a feature install), Felix proceeds to try and refresh all related bundles and always fails with a random ClassNotFoundError. The class not found is different each time.

       

      To reproduce, with a fresh install, wait until all bundles are resolved and blueprints are created, then refresh spring-core. If you're using Felix (the default) it will eventually lock up or commands won't work (e.g. refresh is not a command). Do the same with Equinox and no problems.

       

      In the example below, 78 is Spring Core

       

      karaf@root> refresh 78
      karaf@root> ERROR: Bundle org.springframework.osgi.extender [84] Error stopping bundle. (java.lang.NoClassDefFoundError: org/osgi/framework/ServiceRegistration)

      Killing the process is required at this point.

       

      I've tried adjusting the JVM memory parameters as well but that does not seem to have any affect.

       

      Is this a known issue? I could only find this: https://issues.apache.org/jira/browse/FELIX-3153 which says it was not reproducible.
