When lazy deserialization is on, lock timeouts show MarshalledValue and not actual key

Whenever EntryFactoryImpl can't acquire a lock, it throws:

Object owner = lockManager.getOwner(key);
throw new TimeoutException("Unable to acquire lock after [" + Util.prettyPrintTime(getLockAcquisitionTimeout(ctx)) + "] on key [" + key + "] for requestor [" +
ctx.getLockOwner() + "]! Lock held by [" + owner + "]");

However, when lazy deserialization is enabled, the key is shown in its MarshalledValue form which is useless to the user.

The easy fix is to add:

if (key instanceof MarshalledValue)

{ key = ((MarshalledValue) key).get(); }

However, this is not pretty and the first time we're having to do something similar. We had to do the same in EventImpl for ISPN-242.
