TNS-12518: TNS:listener could not hand off client connection

• When client use SERVICE_NAME = AOFPE001.WORLD -- works fine
• When client use SERVICE_NAME = AOFPE001 -- Does not work
• DB service_names parameter is set to 'AOFPE001.WORLD'
• sqlnet.ora file has parameter set as NAMES.DEFAULT_DOMAIN = WORLD
• So my understanding is when client use SERVICE_NAME = AOFPE001 - the connection should work seamlessly - but we are getting below error in listener.log
