> Entity A has a composite key AId, thus User should look up A with an instance of AId.
> Example: em.find(A.class, new AId());
> In case of looking up A with a single value, for example: em.find(A.class, 12345). It will through an unexpected exception:
> >>>The id type "AId" specfied by persistent type "A" does not have a  public string or class + string constructor.
> >>>>> org.apache.openjpa.kernel.BrokerImpl.newObjectId 
> >>>>> (BrokerImpl.java:1120)

> I suppose to get an exception of error id type.
