When running a Jython script to control the state of an Application Deployed to a Standalone Liberty Profile server, we get the following error: TypeError: javax.management.remote.JMXServiceURL(): 3rd arg can‘t be coerced to int

The reason for this is the line of code in the Jython script that create a connection to the Liberty Server’s JMX interface (WebSphere:service=com.ibm.websphere.application.ApplicationMBean,name=*) is a string not an int i.e. the port number was passed as string not int

The code was changed from
1 2 3 4 5 6 7 | _mBeanConnection = getConnection( trustStore, trustStorePassword, hostname, port, username, password) |
to
1 2 3 4 5 6 7 | _mBeanConnection = getConnection( trustStore, trustStorePassword, hostname, int(port), username, password) |
