Re: [infinispan-dev] [hibernate-dev] Resetting Lucene lock at Directory initialization

On the Lucene side, it seems to me that manually asking for a lock

Yeah, I agree with Emmanuel - a more explicit form would work better
IMO. Perhaps what you could do is something like this:
1) Create an entry, name "sharedlock", value "address of current lock
owner".
2) Any time a node needs a lock, adds its addess to the "sharedlock"
entry only if it doesn't exist (putIfAbsent)
3) If the entry exists , check if the address is still in the cluster
(check using CacheManager.getMembers()). If the address doesn't exist
(stale lock) remove and overwrite (using replace() to prevent
concurrent overwrites)
WDYT?
