Firstly, I added logging to MultithreadedTxTest.Worker.run into catch section:
catch (Exception e)
  |          {
  |             exception = e;
  |             log.error("exception", e);
  |             try
  |             {
  |                tx.rollback();
  |             }
  |             catch (Exception e1)
  |             {
  |                rollbackException = e1;
  |                log.error("rollbackException", e1);
  |             }
  |          }

started test and test passed, but log contains many errors:

Is it all right?

Secondly, I set TransactionManagerLookupClass = "org.jboss.cache.JBossTransactionManagerLookup" and ran test under the running JBoss. I see:
