/**
 * Denote a potential dead lock might occur.
 * More precisely, it occurs if a transaction is waiting a lock too long.
 *
 * <p>How it happens:<br>
 * 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.
 *
 * <p>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.
