the test.print() before test.run() will printout three nulls, which is
correct.
However, after test.run(), the print in finally block will print out: 1 2
null, which means cache.put("test1", "1"); cache.put("test2", "2"); are
successfully written into cache, even though the exception happens. I
thought the tx.rollback() should revert back the values of "test1" and
"test2". It would expect to print out 3 nulls after tx.rollback().
