MetaDataRepository preload doesn't load JAXB meta data
------------------------------------------------------
Key: OPENJPA-1631
URL: https://issues.apache.org/jira/browse/OPENJPA-1631
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.0.0-beta3, 1.2.2
Reporter: Rick Curtis
Assignee: Rick Curtis
The MetaDataRepository preloading doesn't process JAXB xml meta data on EMF
creation, resulting in a condition where multiple threads can trample on each
other. AnnotationPersistenceXMLMetaDataParser.parse(..) isn't thread-safe and
relied on the MetaDataRepository to enforce synchronization. After preloading
is complete, all locks are removed from the MetaDataRepository and in turn
AnnotationPersistenceXMLMetaDataParser can have some threading problems.
Caused by: java.lang.NullPointerException
