Hi,
I noticed that in version 6.0.20 several Hashtables and HashMaps were replaced by ConcurrentHashMaps. I have noticed that many Hashtables were not replaced; therefore, I assume that a contention detection tool was used to identify the contended Hashtables. I would be happy to know if this is the case and also whether a scalability and/or performance improvement was achieved by switching these collections with concurrent ones. Thanks, Ohad
