Gustavo Romero created DAEMON-358:
-------------------------------------

             Summary: PPC64: svc fails to find JVM jvm.cfg file and shared objects due to
wrong path
                 Key: DAEMON-358
                 URL: https://issues.apache.org/jira/browse/DAEMON-358
             Project: Commons Daemon
          Issue Type: Bug
          Components: Jsvc
    Affects Versions: 1.0.13
         Environment: Linux ppc64_machine 3.10.0-505.el7.ppc64le #1 SMP Tue Sep 6 11:09:32
EDT 2016 ppc64le ppc64le ppc64le GNU/Linux, RHEL 7.3
            Reporter: Gustavo Romero
            Priority: Critical



On ppc64 and ppc64le archs jsvc looks for jvm.cfg and JVM shared objects in the wrong path.
Be it used with IBM Java or OpenJDK (where the problem was first encountered), there is no
dir called power64 or power64le. Instead ppc64 and ppc64le are used. In doing so, it fails
with "Cannot find any VM in Java Home"
