Steve we are running into NPE in requestWorkItem.

org.teiid.dqp.internal.process.RequestWorkItem.sendResultsIfNeeded(TupleBatch) - line 753  receiver.receiveResults(response);
receiver is null due to which we are hitting NPE.

As per teiid 8.1 branch it seems to be line 734. http://anonsvn.jboss.org/repos/teiid/branches/8.1.x/engine/src/main/java/org/teiid/dqp/internal/process/

One mroe thing that i observed is batch should contain only 3 rows but there were 4 rows with its last thing as null.

[[3, Always Green Policy, 3, 0, demo_policy_metadata.demo_policy], [3, Always Red Policy, 1, 0, demo_policy_metadata.demo_policy], [3, Always Yellow Policy, 2, 0, demo_policy_metadata.demo_policy], [null, null, null, null, null]]
