The derby.locks.deadlockTrace property causes a detailed list of locks at the time of a deadlock or a timeout to be written to the error log (typically the file derby.log).
For a deadlock, Derby describes the cycle of locks which caused the deadlock. For a timeout, Derby prints the entire lock list at the time of the timeout. This property is meaningful only if the derby.locks.monitor property is set to true.
