> 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:
> {noformat}
