Remarks

Returns the distributed lock instance for the specified key object. The specified object is considered to be the key for this lock. So keys are considered equals cluster-wide as long as they are serialized to the same byte array such as String, long, Integer.

Locks are fail-safe. If a member holds a lock and some of the members go down, cluster will keep your locks safe and available. Moreover, when a member leaves the cluster, all the locks acquired by this dead member will be removed so that these locks can be available for live members immediately.
