             Summary: gogo jline shell completely dies on unexpected tab character
                 Key: FELIX-5449
                 URL: https://issues.apache.org/jira/browse/FELIX-5449
             Project: Felix
          Issue Type: Bug
          Components: Gogo JLine
            Reporter: Bram Pouwelse


Had a quick look at the new org.apache.felix.gogo.jline 1.0.2 that is to be released in an Eclipse project. When a non exising comand is followed by a tab character the console completely dies with the stacktrace below. 

To reproduce just type {{l}} {{\[tab\]}} and hit return
