[jboss-jira] [JBoss JIRA] (JGRP-1684) NPE in UNICAST2.up()

[Radoslav Husar (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12799562#comment-12799562 ] 

Radoslav Husar commented on JGRP-1684:
--------------------------------------

                    case Unicast2Header.ACK:
                        SenderEntry entry=send_table.get(msg.getSrc());

Hm, I assumed msg.getSrc can never be null and if it's null, it is set by transport protocol.
