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
|

def getConnection(trustStore, trustStorePassword, hostname, port, username, password) :
JMXRESTConnector.trustStore = trustStore
JMXRESTConnector.trustStorePassword = trustStorePassword
connector = JMXRESTConnector()
connector.connect(hostname, port, username, password)
mconnection = connector.getMBeanServerConnection()
return mconnection
#endDef

The code was changed from
|
|
_mBeanConnection = getConnection(
trustStore,
trustStorePassword,
hostname,
port,
username,
password)
|
to
|
|
_mBeanConnection = getConnection(
trustStore,
trustStorePassword,
hostname,
int(port),
username,
password)
