Hot undeployment of features does not uninstall all bundles
-----------------------------------------------------------
Key: FELIX-2358
URL: https://issues.apache.org/jira/browse/FELIX-2358
Project: Felix
Issue Type: Bug
Components: Karaf
Affects Versions: karaf 1.6.0, karaf-1.4.0
Environment: Tested on a Windows XP box, with FUSE ESB 4.2 running
Felix as Osgi framework
Reporter: Thomas Demande
When deploying features _via_ the drop-in mechanism (using the
{{FeatureDeploymentListener}}), it also installs needed bundles, as required.
But when the feature file is removed from the deploy directory, some problems
may occur, the most important being that bundles installed by the feature
(only) will not be uninstalled.
An exception is thrown when trying to access the feature bundle entries when
not permitted, resulting in an exception,
I think this is related to what's said in the revision 909487 comment
(http://svn.apache.org/viewvc?view=revision&revision=909487).
That snippet of the class
142 } else if (bundleEvent.getType() == BundleEvent.UNINSTALLED) {
143 try {
144 Enumeration featuresUrlEnumeration = bundle.findEntries("/META-INF/" +
FEATURE_PATH + "/", "*.xml", false);
will always throw an exception as the findEntries has to throw an
IllegalStateException if the bundle in uninstalled.
Therefore, the call to "featuresService.uninstallFeature(f.getName(),
f.getVersion()); " is never reached, and bundled participating in that feature
are not uninstalled.
It's worth noting that in some cases everything is correctly removed, but that
seems to happen only if Karaf has been restarted after the first drop-in of the
feature.
