Jean-Baptiste Onofré commented on KARAF-5592:
---------------------------------------------

We upgraded to jline 3.6.0 recently. The second issue should be fixed now. I'm 
testing the first one (CTRL-C in {{log:display}}). To avoid to hold the release 
for too long, I might postpone the fix to 4.1.6.

> Karaf shell unexpected exit when Ctrl + C during log:display or select text
