Updating an existing VDB via copy-paste in the filesystem causes ConcurrentModificationException ------------------------------------------------------------------------------------------------ Key: TEIID-1276 URL: https://jira.jboss.org/browse/TEIID-1276 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: John Doyle Assignee: Ramesh Reddy If you have a vdb deployed in Teiid and deploy an updated version by pasting the VDB into the deploy directory, a ConcurrentModificationException is thrown. It appears that the original is undeployed, but the new one is not deployed. You cannot connect to the VDB after the exception. 11:51:12,223 INFO [RUNTIME] VDB "Lobs.1[OracleClobs[OracleClobs/oracle/OracleClobs]]" undeployed. 11:51:12,615 INFO [PROCESSOR] Clearing prepared
