Program won't exit (CUCM 10.5)

Q. When I create an application with jtapi, then it will never exit.

I've even created a simple program which just uses the provider, but the program won't exit.

import javax.telephony.*;


public class Startup {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try
        {
            JtapiPeer peer = JtapiPeerFactory.getJtapiPeer(null);
            String providerString = "<server>;login=<user>;passwd=<password>;appinfo=BusyLamp";
            Provider provider = peer.getProvider(providerString);
            
            System.out.format("Started Provider");
            provider.shutdown();
            System.out.format("Provider Shutdown");
            
        }catch( Exception e)
        {
        
        }
    }

}

The main function will return, but the program will never exit.

Am I missing something here or is this a bug?

If you have JDK installed, you can run jconsole to check if there are any threads running.

UseLogFileTraceWriteThread=0

Final Answer:

I've just disabled logging via

                var properties = peer.getJtapiProperties();
                properties.setUseFileTrace(false);
                properties.setUseJavaConsoleTrace(false);

and now it is working as expected
