Symptoms

J2EE applications using Coherence API deployed in 11g FMW domains working well but failing with the CNF exceptions when multiple EAR files having same java package but a different set of classes packaged in the APF-INF/classes folder of the J2EE EAR applications. 

ClassNotFoundException for second-level cache only when Coherence is the stack. Service A and Service B, both services are configured with distributed caches and a backing map scheme of eviction. 

• Request Service A in the first attempt, receive the expected response.
• Request service B in second attempt we receive "java.lang.ClassNotFoundException: xx.xx.xx.XYZSecondLevel".

If request service A in the second attempt, receive the same ClassNotFoundException during response.
