C. Some RV message fields have null or incorrect values in the output of the RV Subscriber activity in BW.


Cause:
The issue happens due to Rendezvous defect (RV-3105) described below:

Java application could abruptly exit while processing a CM or DQ message outside of the dispatch thread.
(Affects only the tibrvnative.jar library.)

Apply Rendezvous 8.4.1 hotfix-01 which fixes this issue:
