what is missing?

So many things.

- Swing

- JavaFX

- NIO and NIO2

- invoke dynamic

- method handles

Are a few that come to my mind, but basically besides from what was left out of Java 6 libraries, almost everything that was introduced in Java 7 and 8.

Swing & JavaFX are not part of the JCL. Those are addon libraries.

NIO: https://developer.android.com/reference/java/nio/package-sum... "added in API 1"

NIO2: https://developer.android.com/reference/java/nio/file/packag...

Invoke dynamic: is a runtime/bytecode thing, not part of the library. The actual feature, lambdas, works just fine on Andorid

Method handles: https://developer.android.com/reference/java/lang/invoke/Met...
