I got 99 problems but a switch() ain't one: Java SE 13 lands with various tweaks as per Oracle's less-is-more strategy

The new switch is nice.

The option to release memory to the OS quickly should help small devices, like cellphones. Hopefully Google hasn't forked the Android JVM innards so it's technologically stuck again.

Preparation for Project Loom (back to the old many:many ratio between Java and Kernel threads) is ambitious but I still need some convincing that the complexity is really worth it. I haven't run out of native threads since 1998. WebSockets involve massive numbers of idle TCP/IP connections but they're message-based so non-blocking I/O isn't too complex for them.
