Description corteggiano CLA 2010-07-20 17:21:03 EDT 
Build Identifier: 7608

org.eclipse.persistence.internal.jpa.QueryHintsHandler, function
QueryHintsHandler$BatchHint.applyToDatabaseQuery(Object, DatabaseQuery, ClassLoader, AbstractSession), lines 1192 to 1205.
While loop iterates over the dot expressions but the line:
DatabaseMapping mapping = descriptor.getObjectBuilder().getMa....
always asks jectfor the mapping ob to the same descriptor (descriptor never changes inside the loop), so second iteration returns null throwing an exception. Previous versions of eclipselink don't have this bug.


Reproducible: Always

Steps to Reproduce:
String  qs = "SELECT e FROM Car e ";
Query q = em.createQuery(qs);
q.setHint(QueryHints.BATCH, "e.engine.brand");

Setting as dup of 320254 because that bug has the contributed patch for this issue.
