StandardExceptoin.unexpectedUserException() does not correctly catch internally generated exceptions
as of JDK 1.6
------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-1629
                 URL: http://issues.apache.org/jira/browse/DERBY-1629
             Project: Derby
          Issue Type: Bug
            Reporter: David Van Couvering


In non-JDK 1.6 builds, the exceptions Derby throws are all of class EmbedSQLException.  As
of JDK 1.6, that is no longer true.  Instead we throw a "native" SQL Exception.

That makes the following code incorrect:

	public static StandardException unexpectedUserException(Throwable t)
	{
		/*
		** If we have a SQLException that isn't a Util
		** (i.e. it didn't come from cloudscape), then we check
		** to see if it is a valid user defined exception range 
		** (38001-38XXX).  If so, then we convert it into a 
		** StandardException without further ado.
		*/ 
		if ((t instanceof SQLException) &&
		    !(t instanceof EmbedSQLException)) 
		{
			SQLException sqlex  = (SQLException)t;
			String state = sqlex.getSQLState();
			if ((state != null) && 
				(state.length() == 5) &&
				state.startsWith("38") &&
				!state.equals("38000"))
			{
				StandardException se = new StandardException(state, sqlex.getMessage());
				if (sqlex.getNextException() != null)		
				{	
					se.setNestedException(sqlex.getNextException());
				}
				return se;
			}
		}

I am not sure how we can detect internally-thrown SQL Exceptions and distinguish them from
user exceptions, but this does need to be looked at.

Right now procedureInTrigger.sql is failing for JDK 1.6 due to this error.  I may check in
a jdk16-specific version of this file so at least derbyall can pass.
