Since I upgraded to b-9, the recovery mechanism hasn't worked once even on new
stores if any transaction read/write is made on the open store before it is
terminated unexpectly. The transaction logs are named tm_tx_log.1 and
tm_tx_log.2. I always get something like this during the recovery process:
Caused by: java.lang.RuntimeException:

I haven't changed anything in my code in the startup/shutdown process before
upgrading. Any ideas on why this is happening all of a sudden?
