Description

If Karaf is shut down in a disorderly way – a VM is terminated for example, or there is a power failure, then on occasion it will fail to restart when the host starts. The problem is that the stored PID in instance.properties might correspond to that of a process that is already running but is not the karaf one.

step to reproduce it:

• Find a PID from an already running process (which is not the karaf one) and place it in instances/instance.properties file as value of item.0.pid key
• Try to start karaf with bin/karaf (or bin karaf.bat)
