Here's the second of my patches.
The DummyTransactionManager uses a ThreadLocal to store transactions. However,
the manager then stores a Map in the ThreadLocal, containing transactions keyed
by Thread. Perhaps I'm missing something, but as far as I can see the Map just
isn't needed as ThreadLocal stores values per thread itself.
Here's a patch against revision 1.14 that removes the offending code.
