>          Issue Type: Bug
>    Affects 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

> 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
