             Summary: Increase the likelihood of ManagedProcess kill invoking the OS kill command when multiple HCs are on the system
                 Key: WFCORE-2073
                 URL: https://issues.jboss.org/browse/WFCORE-2073
             Project: WildFly Core
          Issue Type: Enhancement
          Components: Domain Management
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
            Priority: Minor


The ManagedProcess kill() method relies on a scan of running processes that have a command line with -D[<processname>] in the command line, refusing to do the OS kill if > 1 such process is found.

This is troublesome if you have > 1 HC on the machine, as they are likely to use the same process names (e.g. "Server:server-one"). So the 'kill' doesn't happen, and destroy() gets used instead. Destroy doesn't seem as strong, as it seems to not prevent shutdown hook execution, leaving open the possibility of hangs.

Perhaps the PC could generate a random int or even a short and include that as a param on the command line as well, then use that as part of the discrimination check.
