[jboss-jira] [JBoss JIRA] (WFLY-6312) Intermittent failure: client gets NPE in ejbremote scenario

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-6312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13170819#comment-13170819 ] 

David Lloyd commented on WFLY-6312:
-----------------------------------

An NPE is always a bug.  In this case it is in Remoting, so the upstream JIRA should be opened in the REM3 project (ideally including the exact version of Remoting that this problem was observed in).
