Subject [jira] [Commented] (KARAF-5092) An Invalid input during log:tail results in blocking keyboard inputs.

Peter Huffer commented on KARAF-5092:
-------------------------------------

I'm not sure if this is related, but I've run into an issue on windows where if I do `log:tail`
and press `ctrl+c` before the log is finished printing previous logs, it will crash the process.

Since Ctrl+D is ignored at this state, the only way to quit karaf is to kill the java process.
