Public bug reported:
---Problem Description---
jsvc, an application to launch a java daemon, on ppc64 and ppc64le 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"
---uname output---
Linux vm 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:38:24 UTC 2016 ppc64le
ppc64le ppc64le GNU/Linux
Machine Type = pKVM
---Debugger---
A debugger is not configured
---Steps to Reproduce---
# apt-get install libcommons-daemon-java jsvc
# 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...");
}
}
# javac MyClass.java
# jar cvf my.jar MyClass.class
# sudo jsvc -debug -user root -java-home
/usr/lib/jvm/java-1.8.0-openjdk-ppc64el -cp
/usr/share/java/commons-daemon.jar:/root/my.jar MyClass -start
