I also marked the existing ThreadPoolTaskSchedulerBuilder constructor with the @Deprecated annotation, as I believe the public modifier was added unintentionally.

I set the version to since 3.5.0, but if possible, could this be merged into 3.4.0 instead? Of course, if you have time.

Thanks @nosan. We're post RC now so we won't merge additional enhancements.
