Why was PaddedAtomicLong removed?

John said...

Just found this as a possible answer to why PaddedAtomicLong was removed:

It seems that Java 7 behaves differently to previous versions so Padding does not work like it used to.

The point of the padding is to prevent more than one thread sharing the same cache line and in so doing remove contention.

Sequence and PaddedAtomicLong have the same role (cache friendly atomic counter), so it was a refactoring toward a common implementation.
