Java Service Wrapper

Hello, Im a student implementing Hackystat.org' s SOA services with JSW using integration method 3.
I implemented a WrapperListener on mac osx which starts a RESTLet Service in a Jar.
I pass the Listener to the WrapperManager after setting the configuration properties via System.setProperty(...).
It seem like The service gets started (even the debug says "Not using wrapper"), but there is no way to shut it down anymore, even not with the kill command. The WrapperManager.start() never returns but the SOA service gets started properly. In VisualVM i cant see any new JVM but I guess thats normal because its stared as unix service.

Properties set:
System.setProperty("wrapper.java.mainclass","SensorBaseExecutionAgent");
System.setProperty("wrapper.java.classpath.1","../lib/wrapper.jar");
System.setProperty("wrapper.java.library.path.1","../lib");
System.setProperty("wrapper.java.additional.auto_bits","TRUE");
System.setProperty("wrapper.debug","TRUE");
System.setProperty("wrapper.console.format","PM");
System.setProperty("wrapper.console.loglevel","INFO");
System.setProperty("wrapper.logfile","../logs/wrapper.log");
System.setProperty("wrapper.logfile.format","LPTM");
System.setProperty("wrapper.logfile.loglevel","INFO");
System.setProperty("wrapper.logfile.maxsize","0");
System.setProperty("wrapper.logfile.maxfiles","0");
System.setProperty("wrapper.syslog.loglevel","NONE");
System.setProperty("wrapper.console.title","sensorbase");
System.setProperty("wrapper.ntservice.name","sensorbase");
System.setProperty("wrapper.ntservice.displayname","sensorbase");
System.setProperty("wrapper.ntservice.description","thisissensorbase");
System.setProperty("wrapper.native_library", "wrapper");
System.setProperty("wrapper.version", "3.3.5");

Console:

Anyway, it says that it returned but I am not able to stop it and my method calling WrapperManager.start never returns and everything is frozen.

Thank you a lot for your help.
Best Regards,
