With Java 9, Java finally supports HiDPI on Linux and Windows. MacOS has had HiDPI support since Java 7u40. On Linux it also adds GTK support.

Installer is digitally signed August 3rd, why such a long delay until release?

Speculating here, but perhaps they had planned some additional testing and wanted to have plenty of time to fix bugs.

Looks like they just gave themselves quite a bit of time for testing. http://mail.openjdk.java.net/pipermail/announce/2017-Septemb...

Android Studio 2.3 and the corresponding gradle versions embedded in android projects throw a hissy-fit on this java version. Android studio refuses to select the jdk9 directory (says "Please use JDK 8 or newer"), and gradlew quickly fails with "Parsing the SDK, no caching allowed, Failed to notify project evaluation listener, javax/xml/bind/annotation/XmlSchema"...?

I was pretty excited about AOT compilation⁰, but it seems it doesn't support dynamically generated classes and bytecode i.e.: lambdas and invokedynamic.

They've changed the version string⁰ format. Existing software needs to be updated to parse the new format.

Will JVM ever play with the browser again? https://twitter.com/globalmaxima/status/908089963752808448

It would be great if Oracle licensed & worked to get bytecode into chromium and Microsoft did likewise with cil. It will take wasm 10 years to mature anywhere near those two. It'd be nice to not have to wait.

It is work in progress, the Java 10 dev branch already has much better support, including macOS and Windows, according to the Java Languages Summit 2017 talks.

In any case, the other JDK vendors with AOT support are still around.
