/**
* <p>
* Regression test case for DERBY-5562.
* </p>
*
* <p>
* The timer that aborts long-running transactions if a transaction timeout
* has been specified, was not cancelled when preparing a read-only
* transaction. Since read-only transactions are implicitly committed when
* they are prepared, this meant that the timer would try to abort an
* already completed transaction. In addition to printing a confusing
* message in db.log about the transaction being rolled back, when it
* actually had been committed, this could also make the timer roll back
* the wrong transaction, if a new transaction with the same Xid was
* started later.
* </p>
*
* <p>
* This test case exposes the bug by running a read-only transaction with
* a timeout and preparing it, and then starting a new transaction with the
* same Xid and no timeout. The bug would cause the second transaction to
* time out.
