public class PotentialDeadLockException
extends OperationException

Denote a potential dead lock might occur. More precisely, it occurs if a transaction is waiting a lock too long.

How it happens:
Transaction A writes bean X and transaction B writes bean Y, and then A tries to read or write bean Y and B tries to read or write bean X.

This exception shall be rare, because CmpManager sorted beans to be updated in a special order. However, it still might happen, because a transaction might trigger multiple syncBeans.
