[jboss-jira] [JBoss JIRA] (AS7-5363) NPE on tab completion

[Alexey Loubyansky (JIRA)]

    [ https://issues.jboss.org/browse/AS7-5363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712170#comment-12712170 ] 

Alexey Loubyansky commented on AS7-5363:
----------------------------------------

This one is fixed now as well. It didn't manifest itself in the master, probably, because the master is using jreadline for terminal and keyboard binding instead of jline in 7.1. But the change was applied to both branches. Thanks.

> iirc, the previous behaviour (that I was expecting) was to propose completion for the resource children.
