The lock will automatically be collected by the garbage collector when the lock is released and no other waiting conditions exist on the lock.

Hazelcast does not automatically perform garbage collection in the lock.
This can lead to an OutOfMemoryError.
If you create locks on the fly, make sure they are destroyed.
