I’m using JPA in my project but receiving an exception related to JDO classes and I saw this in other occasions, also.
I don’t want to know about this specific exception in the JDOStateManagerImpl class, I want to know if it’s normal to receive exceptions related to JDO when using JPA or I’m messing with the configurations.
I know DataNucleus is the provider for both so I thought that even using JPA, JDO would be doing the job behind the scenes.
It’s normal to receive exceptions when things happen that the JPA spec says throw an exception for. A nested exception can be a JDO exception (or a DataNucleus exception or a lowlevel exception) since the JDO bytecode enhancement contract is utilised (that is the only part of JDO present here, and since it is a standardised bytecode enhancement contract is a very sensible thing to make use of instead of inventing a new contract).
