Hello,
after activating deadlock detection with 500 ms of spin duration, i launch a classic deadlock scenario.
Node 1 acquire local lock.
Node 1 try to acquire cluster wide lock.
Node 2 acquire local lock.
Node 2 try to acquire cluster wide lock. 
Then deadlock is not detected and the TimeoutException occurs:
org.infinispan.util.concurrent.TimeoutException: Unable to acquire lock after [20 seconds] on key [counter_key] for requestor [DldGlobalTrans
action{coinToss=3136454835479173852, isMarkedForRollback=false, lockIntention=counter_key, affectedKeys=[counter_key], locksAtOrigin=[]} Glob
alTransaction:<nodeDeadLock-11465>:5:local]! Lock held by [DldGlobalTransaction{coinToss=3164596253027655679, isMarkedForRollback=false, lock
Intention=null, affectedKeys=[], locksAtOrigin=[]} GlobalTransaction:<nodeDeadLock-16603>:1:remote].

I give my configuration file for ISPN and a Class TwoNodesDeadlocks.java  to reproduce the problem.
