Serialization problem with Hazelcast Maps & Locks

[bradhouse]

I'm wondering if this is broken again on 1.7.1.

From:

final IMap<String, Long> counter = Hazelcast.getMap("count");
ILock counterLock = Hazelcast.getLock(counter);

.getLock() causes:

Possible as of 1.8 we added a test for it so that we don't break it again.
http://code.google.com/p/hazelcast/source/browse/trunk/hazelcast/src/test/java/com/hazelcast/impl/ClusterTest.java#860

1.8 is highly recommended or even wait about a week for 1.8.1 which is
much stronger.
