[jira] [Created] (OAK-2294) Corrupt repository after concurrent
version operations
Michael Dürig created OAK-2294:
----------------------------------
Summary: Corrupt repository after concurrent version operations
Key: OAK-2294
URL: https://issues.apache.org/jira/browse/OAK-2294
Project: Jackrabbit Oak
Issue Type: Bug
Components: jcr
Reporter: Michael Dürig
Priority: Blocker
Performing version operations (checkin / checkout / addVersionLabel) concurrently can corrupt the repository.
Executing the following code in parallel from multiple threads demonstrates this:
{code}
Version version = versionManager.checkin(vPath);
versionManager.checkout(vPath);
String label = version.getName() + " " + Thread.currentThread().getName();
version.getContainingHistory()
.addVersionLabel(version.getName(), label, true);
{code}
In my tests this eventually lead to all sorts of exceptions:
