[jboss-jira] [JBoss JIRA] (JGRP-2282) Frequent "received message without encrypt header from Y; dropping it" with both ASYM_ENCRYPT and SYM_ENCRYPT

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-2282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13619298#comment-13619298 ] 

Bela Ban commented on JGRP-2282:
--------------------------------

Hmm, can you reproduce this? When a message is encrypted, it is actually *copied*, and the copy is encrypted and sent, to prevent multiple encryption when a message is retransmitted.

On the receiver side, in both NAKACK2 and UNICAST3, messages are decrypted and passed up, but *not* retransmitted, as this happens only on the sender side.

I cannot see how a message or message batch would end up not having an encrypt header...

> There seems to be a regression (in 4.0?) in SYM_ENCRYPT and ASYM_ENCRYPT dropping messages around topology changes (and possibly bypassing retransmission?). QE tests using these protocols observe a lot of the following:
