I checked out JBM trunk source, and verified that I got the fixed code. I rebuilt and tested, and got the same error. I re-read the bug report, and here's the concern that I have: It says that the problem occurs on redelivery of a message. Since I'm using only MDBs, I would assume that redelivery can only occur when it's tried already and failed - yet I don't see any prior exceptions. Could the error (internal stream pointers not set properly) occur on a first delivery? Or a delivery to multiple subscribers? Could there be something wrong with the message acknowledgement in the MDB? Thanks, Rick View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100805#...
