[jira] [Commented] (FELIX-3318) NPE in WebConsole when trying to
uninstall a bundle
[ https://issues.apache.org/jira/browse/FELIX-3318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13193849#comment-13193849 ]
Felix Meschberger commented on FELIX-3318:
------------------------------------------
I think this is a bug in the PackageAdminImpl.getBundleType method: This calls adapt to get the BundleRevision of the bundle which returns null for uninstalled bundles (probably correctly). Yet this result is not checked in the getBundleType method and thus the NPE.
