Andy Dale commented on HHH-2159:
--------------------------------

Ok, i have figured out the one of the entries that is iterated through in the method

private FromElement findIntendedAliasedFromElementBasedOnCrazyJPARequirements(String specifiedAlias) {

		//System.out.println("SpecAlias was: " + specifiedAlias);

               Iterator itr = fromElementByClassAlias.entrySet().iterator();

               System.out.println("Iterator (FromElement): " + itr.toString());

	       while ( itr.hasNext() ) {

			Map.Entry entry = ( Map.Entry ) itr.next();

			String alias = ( String ) entry.getKey();

                        System.out.println("Alias = " + alias);

			if ( alias.equalsIgnoreCase( specifiedAlias ) ) {

                              System.out.println("Return value: " + entry.getValue());
                              

			      return ( FromElement ) entry.getValue();

			}

		}


		return null;

	}

This is the cause of all the problems i was having, putting the call to this method from within the containsClassAlias method in a try catch block solves this problem.  I  don't think i will have the time to find the underlying cause of this problem (where the map is populated).

If you need anymore info please get in touch

>          URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2159
>      Project: Hibernate3
>         Type: Bug

>     Versions: 3.2.0.ga
>  Environment: hibernate 3.2.0GA, PostgreSQL 8.1.4 (using build 407 of the JDBC driver).  JDK 1.5.0_06, JBoss 4.0.4GA, Operating system is Fedora Core 5
>     Reporter: Andy Dale
>  Attachments: hibernate_testcase.tar.gz

> First off i do not know if this bug belongs to the Hibernate3(core) or Hibernate EntityManger branch, but have entered it against core because that is where the exception occurs (in org.hibernate.hql.ast.tree.FromClause.findIntendedAliasedFromElementBasedOnCrazyJPARequirements).
> I have a relativley simple entity setup up to test a proof of concept.  Persisting the data to the database is not a problem in the new version 3.2.0.GA, but the problems occurs when trying to perform a query on the persisted data, the very same query works with 3.2.0CR2 but gives a nullPointException in 3.2.0GA.
> I have attached the java source for the entities + session bean (in hibernate_testcase.tar.gz/entities file) and the java class (in hibernate_testcase.tar.gz/service file) that is used to persist and query the data, and because this was only meant to be a proof of concept i have also included the .ear archive as apart from the entity definitions and session bean the only other thing it contains is a JBoss .sar archive which calls the static persist and query methods in the session bean (service test.testcase).  Please note to use the .ear archive you need a datasource called Postgres_Test
