+0. It's just another alternative way. It's hard to say it's an optimization？

Yes. It's not really an optimization, just a simplification of the code

Thank you for your contribution.

In my opinion this kind of patches is not worth to be committed.
'Don't fix things that are not broken' is a good motto.

This change does not add much value, but it my affect the execution at runtime.
It may look like nitpicking but it is a broader thought.
We should change code only if there is a good reason do to it.
Even in this case the behaviour may be different for some JVM, so why risk to break things?

@lanicc I encourage you to submit other patches, it is very appreciated here, but it is better to pick up some known issue and try to fix it or if we want to reduce our technical debt probably it is better to pick up a topic (using method references?) and address the problem more globally
