------------------------------------

             Summary: ClassCastException - AbstractResource cannot be cast to AbstractBundleRevision
                 Key: JBOSGI-563
                 URL: https://issues.jboss.org/browse/JBOSGI-563
             Project: JBoss OSGi
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Core Framework
    Affects Versions: JBossOSGi 1.3.0
            Reporter: Rico Neubauer
            Assignee: Thomas Diesler


Occurs with JBoss 7.1.2.Final (EAP) running with jbosgi-framework 1.3.0.Final

Unfortunately not sure about the conditions - a vanilla JBoss does not show the symptom, I assume it depends on how bundle dependencies are defined, or on capability usages. Will try to find out more, but the following presents an issue anyway:

Accessing bundles may throw a ClassCastException in:
- org.jboss.osgi.framework.internal.HostBundleState#getDependentBundles()
- org.jboss.osgi.framework.internal.PackageAdminPlugin.ExportedPackageImpl#getImportingBundles()
- There are other places of unchecked casts to AbstractBundleRevision, but they may be OK.

The following occurs when accessing the problematic bundles via felix web-console:

Will attach a fix for those two locations.
