Subject [jira] Created: (JCR-1480) Deadlock when executing Version operations
Date Mon, 17 Mar 2008 09:57:24 GMT
Deadlock when executing Version operations

                 Key: JCR-1480
                 URL: https://issues.apache.org/jira/browse/JCR-1480
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-core, versioning
    Affects Versions: core 1.4.1, 1.4
            Reporter: Marcel Reutegger
            Priority: Minor

This only happens when a XA transaction is committed without changes. In XAVersionManager
there is a check in the InternalXAResource returned by getXAResourceBegin(), which only acquires
the write lock on the version manager if there are version related changes in the transaction.
This kind of check is missing in the methods XAVersionManager.prepare/commit/rollback().
