GoogleCodeExporter commented 9 years ago 
Today I got this error in logs:

03 Feb 2012 08:38:49,007 ajp-0.0.0.0-8109-11 ERROR () 
[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/pithos].[RESTH
andler]] Servlet.service() for servlet RESTHandler threw exception
javax.ejb.EJBTransactionRolledbackException: Transaction rolled back

As I mentioned in issue 112, there are times when two threads try to modify the 
same resource (folder or file) directly or indirectly (e.g. one thread modifies 
a file and the other modifies the containing folder) causing 
OptimisticLockExceptions by hibernate which in turn cause the transaction to 
rollback. Gss catches the exceptions and retries the transaction. Therefore, 
there is nothing to be fixed. Probably, we shouldn't log them anyway.
