JPA Entity Manager persist() Method Does Not Throw EntityExists Exception (Doc ID 1570151.1)

Last updated on APRIL 06, 2018

Applies to:

Oracle Weblogic Server - Version 12.1.1.0 and later
Information in this document applies to any platform.

Symptoms

A stateless EJB bean is having a method (createInt) where an entity (Vehicle)  is persisted via JPA API :

the expected behaviour is that the exceptions received are extending EntityExistsException
or PersistenceException exceptions.

The problem is :
  1/ The EJB exception does not contain any EntityExistsException or PersistenceException
  2/ The nested exceptions of EJBException by calling getCausedByException does not extend EntityExistsException or PersistenceException exceptions.
