Date Mon, 17 Oct 2016 13:11:58 GMT

     [ https://issues.apache.org/jira/browse/FELIX-5382?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pierre De Rop closed FELIX-5382.
--------------------------------
    Resolution: Invalid

oops, just realize that when using jline, you must not install the gogo shell, and I have
not anymore the NPE with the following bundles:

{code}
    1|Active     |    1|JLine (3.0.0)|3.0.0
    2|Active     |    1|Apache Felix Bundle Repository (2.0.8)|2.0.8
    3|Active     |    1|Apache Felix Gogo Command (1.0.0)|1.0.0
    4|Active     |    1|Apache Felix Gogo JLine Shell (1.0.0)|1.0.0
    5|Active     |    1|Apache Felix Gogo Runtime (1.0.0)|1.0.0
{code}

cancelling this issue ... sorry.
