                 URL: https://issues.jboss.org/browse/AS7-5363
             Project: Application Server 7
          Issue Type: Bug
          Components: CLI
            Reporter: Jeff Mesnil

I encountered this issue on 7.1 branch

When pressing TAB to get autocompletion on a path that has already been autocompleted, it throws a NPE.

$ ./bin/jboss-cli.sh
[disconnected /] connect
[standalone at localhost:9999 /] cd /subsystem=me<TAB>
=> this works and completes the "messaging" address
[standalone at localhost:9999 /] cd /subsystem=messaging<TAB>
=> this throws an NPE
java.lang.NullPointerException

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