-----------------------------------
Summary: Journal doUnlock sometimes not called on repository
shutdown
Key: JCR-3406
URL: https://issues.apache.org/jira/browse/JCR-3406
Project: Jackrabbit Content Repository
Issue Type: Improvement
Reporter: Thomas Mueller
Assignee: Thomas Mueller
When the repository is shut down, the method AbstractJournal.doUnlock(boolean
successful) is sometimes not called. The method Journal.close is called, but
when the journal implementation uses a reentrant lock it can't unlock because
close is called from a different thread.
The reason for not calling doUnlock is that ClusterNode.stop() sets the status
to "stopped", which causes all WorkspaceUpdateChannel methods to not work,
including updateCommitted and updateCancelled. Therefore, it is possible that
an operation is started but never completed nor cancelled.
To solve the issue, I found that it is enough to let updateCommitted and
updateCancelled to complete, so that operations that are in progress can finish.
