Solution:

1) Check the folder structure of your connector server

2) Remove any other jars from bundles folder and keep only bundle jar in it.

In my case, somebody kept supporting jars as well in the same folder along with my bundle jar(org.identityconnectors.dbum-12.3.0.jar)

java.net.BindException: Address already in use: JVM_Bind

While Starting the Connector Server Seeing below mentioned error:

Solution:

1) Go to ConnectorServer.properties and check the port

2) there must be something running on the same port.

OR

3) your connector server is up and running

4) kill the process and restart the connector server.
