      Regression Test Failure, Wrong query result

      Description

      I ran a randomized test for nested joins against PostgreSQL, Derby, and H2, and found some problems with Derby. The queries below throw NullPointerExceptions; the last query an assertion. The test case is here: http://code.google.com/p/h2database/source/browse/trunk/h2/src/test/org/h2/test/db/TestNestedJoins.java . There are probably shorter queries that are problematic, but I can't test it because Derby closes the connection after the assertion.
