public class LockDeadlockException
extends LockTimeoutException

This exception is used by the lock manager to indicate that it detected a deadlock. It prevents the deadlock by throwing this exception. Typically, this deadlock is a result of the following scenario: one transaction owns a weaker lock as a result of getting a map entry, and then, at commit time, the transaction attempts to promote the weaker lock to a stronger lock in order to apply the changes to the data store. For example, two transactions try to promote from shared locks to exclusive locks but each transaction already owns a shared lock.
