CustomizableThreadCreator could use AtomicInteger [SPR-11103]

[spring-projects-issues]

Phil Webb opened SPR-11103 and commented

Customizable thread creator should use an AtomicInteger for a single and incrementing counter, for elastic thread pools locking for a single thread creation is at least twice expensive than using any AQS implementation.

I have to open an issue for this, sorry for starting on a wrong foot. Will do that soon.

I've added this improvement to master, for release in 4.0.2. I'm reluctant to backport it to the 3.2.x branch since it's a runtime improvement and not a bug fix...
