Re: PAX-HTTP-WHITEBOARD hangs on Karaf 4.1.2

[Maurice Betzel]

Just returned from my Holidays and tried Karaf 4.1.5 having upgrades 
toJLine 3.6.0 and Jansi 1.17.
Pax Web 6.1.2 now installs perfectly.

Re: PAX-HTTP-WHITEBOARD hangs on Karaf 4.1.2

OK, just tested 6.1.1 with the same result. It seems as jline is blocking.
I can type text on the console but the commands are ignored, the cursor has 
other strange behavior as well, like not shutting down Karaf with ctrl.
If i drop a bundle in the deploy folder it gets deployed as usual. After a 
hard kill and restart the deployed bundle are present as is pax-web 6.1.1.
Now everything is working as expected.

Hi,

are you sure it really hangs, or is jline and therefore the shell not
responsive anymore.
