[jboss-jira] [JBoss JIRA] (AS7-3792) Remote EJB client still throws exception rather than blocking

Thu Mar 8 08:37:37 EST 2012

    [ https://issues.jboss.org/browse/AS7-3792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675127#comment-12675127 ] 

jaikiran pai commented on AS7-3792:
-----------------------------------

The code to make sure that only the allowed number of channel messages are sent from the EJB client, is in place. The reason for why this exception still occurred with this code in place was investigated in https://issues.jboss.org/browse/AS7-3796. I'm marking this as duplicate because there wasn't anything done specific to this issue and there's no more safeguard that can be added from a EJB client API implementation point of view.
