@RogerRiggs, @minborg, @naotoj, thanks for the reviews. I've attached successful `tier1,2` results to the ticket. I'd appreciate it if one of you would be kind enough to also sponsor the changes.

@wenshao, thanks for the tip. I will explore if we can perform similar simplifications in `java.util` too.
