Enterprise WebBeans w/ PersistenceContext throw incorrect exception when failing
--------------------------------------------------------------------------------

                 Key: WBRI-275
                 URL: https://jira.jboss.org/jira/browse/WBRI-275
             Project: Web Beans
          Issue Type: Bug
    Affects Versions: 1.0.0.PREVIEW1
         Environment: Suse 11.1 and SLES 10.2
Java 6 64 Bit JDK
JBoss AS 5.1
            Reporter: John Ament
            Priority: Minor


If you create an enterprise web bean with a logical error, i.e. attempting to play with the transaction from within a method or attempt to access a table that does not exist, you get a stack trace that only mentions:

java.lang.IllegalArgumentException: enterpriseBeanInstance.setDestroyed() called with non-boolean argument


This is incorrect, or at least undesirable, because there's no clear indication where the error actually lies.

Examples of the poor programming:
Referencing an entity bean that has @Table("some_non_existent_table")
Starting a transaction:

entityManager.getTransaction().begin();
Query q = entityManager.createQuery("select i from Image i where i.skuAssociated = :sku").setParameter("sku", sku);
List<Image> results = q.getResultList();
entityManager.getTransaction().commit();
return results;

Essentially, anything that can cause a RuntimeException (or child of) to be thrown from within the methods of a Stateful EJB.

To test:

Create a standard EJB w/ a similar programming problem and see that it does not throw this exception.
Create an enterprise web bean w/out this programming problem and see that it does not throw this exception.
