multithreaded JunitTest

Hi,

I'm reenabling some disabled JUnitTests in dbaccess/JunitTest_dbaccess_complex.mk
And finding (and fixing) several bugs on the way.

In particular, in dbaccess/qa/complex/dbaccess/RowSet.java:

    void testConcurrentAccess(XResultSet _resultSet)
    {
            (...)
            for (int i = 0; i < numberOfThreads; ++i)
            {
                threads[i] = new Thread(new ResultSetMovementStress(createClone(), i));
                System.out.println("starting thread " + (i + 1) + " of " + (numberOfThreads));
                threads[i].start();
            }

            for (int i = 0; i < numberOfThreads; ++i)
            {
                threads[i].join();
            }
    }


My problem is that the launched threads fail in this way:

        public void run()
        {
            try
            {
            }
            catch (Exception e)
            {
                fail("ResultSetMovementStress(" + m_id + ") failed " + e);
            }
       }


But the test as a whole still succeeds! The subthread failure is just
ignored.

I fixed the underlying bug, but I would like to fix the test so that
it fails when one of the threads fails. I tried to not catch the
Exception, but that does not help. (I noticed the thread failure by
looking at workdir/JunitTest/dbaccess_complex/done.log )

How do I fix this?

Thanks in advance for any help,
