EJB Miss Counts At 100% When MDB Does not Explicitly Specify Implements MessageListener

Applies to:Oracle WebLogic Server - Version 10.3.5 to 184.108.40.206.0
Information in this document applies to any platform.
Using the WebLogic console application, some Message Driven Beans are having a miss total count at 100%. At code level, the Message Driven Bean is explicitly declaring the class as implements MessageListener had a near zero miss total count. Those MDSs that use the ‘messageListenerInterface = MessageListener.class’ attribute on the @MessageDriven annotation were the ones that were never hit in the cache.
Consider the following instructions to replicate this problem:
1. Create a brand new WebLogic Server domain
2. Create JMS resources, including a factory and a queue with JNDI name:
MyConnectionFactory and MyQueue
3. Create a Message Driven Bean, with the following code:
7. Redeployed the Message Driven Bean, with the remotion of implements MessageListener
8. Sent another 10 messages to the queue, 'Miss Total Count' accumulated to 10
