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: Steven Hawkins
Priority: Minor
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.
