On: JDK 21 Release Notes

[jlnho]

Enterprise ETL/CRUD stuff and (some) native Android applications.

[yankput → jlnho]

Android doesn’t follow the Oracle Java though, right. So all these new features are just not there, right

[bad_user → yankput]

The compile-time features end up being supported. The runtime features (e.g., invokeDynamic) less so.

OTOH, Android would benefit from virtual threads, too, which is one of the reasons they've jumped feet-first on the Kotlin train (and Kotlin's coroutines are pretty well designed).

[charcircuit → yankput]

It uses their compiler javac. Then the class files get compiled into dex files for androids runtime.

[jlnho → yankput]

Not yet, I believe they currently support everything (or nearly everything) up to Java 11.
