Unclear exception if an unknown external value is used
------------------------------------------------------
Key: OPENJPA-416
URL: https://issues.apache.org/jira/browse/OPENJPA-416
Project: OpenJPA
Issue Type: Bug
Affects Versions: 1.0.0, 0.9.7, 0.9.6
Reporter: Michael Dick
Priority: Minor
Fix For: 1.0.1, 1.1.0
If you have specified ExternalValues for a field in an entity the transaction
will be rolledback, but the root exception doesn't provide any information on
what went wrong.
Here's an example :
<openjpa-1.1.0-SNAPSHOT-r420667:587896M fatal store error>
org.apache.openjpa.persistence.RollbackException: null
at
org.apache.openjpa.persistence.EntityManagerImpl.commit(EntityManagerImpl.java:469)
at
mdd.tests.TestExternalValues.testUnrecognizedExternalValue(TestExternalValues.java:40)
<snip>
Caused by: <openjpa-1.1.0-SNAPSHOT-r420667:587896M nonfatal general error>
org.apache.openjpa.persistence.PersistenceException: null
at
org.apache.openjpa.kernel.BrokerImpl.beforeCompletion(BrokerImpl.java:1778)
<snip>
... 19 more
Caused by: java.lang.NullPointerException
at
org.apache.openjpa.kernel.StateManagerImpl.fetchInt(StateManagerImpl.java:2168)
at
org.apache.openjpa.jdbc.meta.strats.PrimitiveFieldStrategy.update(PrimitiveFieldStrategy.java:157)
<snip>
... 23 more
The exception should be made more meaningful.
