The Teiid client jar was added to the build process of the Teiid Jopr plugin's lib folder. This was needed to support Teiid in a JON instance. This jar is causing errors in JBossAS 5.1 and is not required for Jopr so it should be removed from the community build. The product build needs to be changed to add the jar and https://jira.jboss.org/browse/SOA-2609 was logged to address this change.
