Description

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"

A debugger is not configured

Steps to Reproduce:
yum install apache-commons-daemon-jsvc

1. cat MyClass.java
   public class MyClass {
   public void init(String[] args) { System.out.println("Init..."); }

public void start()

{ System.out.println("Start..."); }

public void stop()

{ System.out.println("Stop..."); }

public void destroy()

{ System.out.println("Destroy..."); }

}

1. javac MyClass.java
2. jar cvf my.jar MyClass.class
3. /bin/jsvc -debug -user root -java-home /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-2.b15.el7_3.ppc64le -cp /usr/share/java/apache-commons-daemon.jar:/root/my.jar MyClass -start
