I’m trying to run a java daemon using jsvc and the Daemon interface. The java project is
a jar file which has a bunch of dependencies in a manifest file (including commons-daemon),
and I add this jar file to the classpath when running jsvc.
 When I try to execute via jsvc however, I get this stacktrace in stderr:
java.lang.InstantiationException: com.mycomany.mypackage.MyClass
        at java.lang.Class.newInstance(
17/07/2014 17:03:34 9904 jsvc.exec error: Cannot load daemon
17/07/2014 17:03:34 9903 jsvc.exec error: Service exit with a return value of 3
Where MyClass is the class that I pass into jsvc.
I have tried using the –verbose option to help diagnose the problem, and with that I can
see in stdout that it loads all the dependencies from the manifest just fine, but no additional
information is provided to help diagnose the problem.
 Is there a way to get more information about what causes this InstantationException?
