public class LocalDeadlockDetectedException
extends org.neo4j.kernel.DeadlockDetectedException

Temporary exception to aid in driving out a nasty "lock get stuck" issue in HA. Since it's subclasses DeadlockDetectedException it will be invisible to users and code that already handle such deadlock exceptions and retry. This exception is thrown instead of awaiting a lock locally on a slave after it was acquired on the master, since applying a lock locally after master granted it should succeed, or fail; it cannot wait for another condition. While this work-around is in place there is more breathing room to figure out the real problem preventing some local locks to be grabbed.
