Key: JCR-2131
URL: https://issues.apache.org/jira/browse/JCR-2131
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Environment: Linux
Reporter: Lorenzo Pavesi
during concurrent workspace move in cluster jackrabbit environment i
get a deadlock, (moving different node from different source to the
same destination directory). I get the same problem using also the session move.
Follow a stack trace:
