bad query results exposes IllegalArgumentException instead of an HibernateException
-----------------------------------------------------------------------------------

         Key: HHH-2187
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2187
     Project: Hibernate3
        Type: Bug

  Components: query-hql  
    Reporter: Max Rydahl Andersen


s.createQuery("kkk");

results in an IllegalArgumentException being thrown making the exception bubble
through the expected catch HibernateException clauses in e.g. the tools.


Cause is:

public void traverseDepthFirst(AST ast) {
		if ( ast == null ) {
			throw new IllegalArgumentException( "node to traverse cannot be null!" );
		}
		visitDepthFirst( ast.getFirstChild() );
	}

in NodeTraverser.

java.lang.IllegalArgumentException: node to traverse cannot be null!
