Ramesh Reddy resolved TEIID-763.
--------------------------------
Resolution: Done
Node not valid exception is happening because of the setTimeLimit is set to zero (0),
which should be unlimited (-1)
NPE, from the JBoss cache code there is no way to avoid it, as t happens during the thread
interruptions or when a node is deleted. So if this is occurring in the "remove"
situations handle them appropriately, otherwise it will still fail with a meaningful
message
Exceptions from cache under load
--------------------------------
Key: TEIID-763
URL: https://jira.jboss.org/jira/browse/TEIID-763
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 6.1.0
Reporter: Steven Hawkins
Assignee: Ramesh Reddy
Fix For: 6.2.0
The following exceptions happen occasional under load. These exceptions are mostly
cosmetic though, since they are happening only during removal.
Exception in thread "Worker5" java.lang.NullPointerException
