I'm reopening the bug because ultimately this issue will have to be
fixed, but I'm lowering the severity to prevent the autoremoval.

The current plan is to only ship OpenJDK 11 in Buster but I can imagine
that we keep OpenJDK 8 just for building packages but depend on OpenJDK
11 at runtime. OpenJDK 8 will be supported until 2020 but even without
support it should be safe to use for development purposes. Ok, let's
keep that in mind and see what happens.

Regards,

Markus

Does anyone know what the plan is for openjdk-8 in buster?  If it
isn't going to go away, the easiest thing may be to depend on it
instead of default-jdk.

It look like after many years now, no one has tried to put together a
kotlin compiler package, so supporting lwjgl3 seems very unlikely.

Best wishes,

I had a go at this today. This package has multiple issues. I tried to
work around the RuntimeExceptions by returning true instead of throwing
an exception. Very bad I know.

It turned out that not only one but four classes are not properly
generated at build time. Those will cause missing symbol errors later.
Then there are several removed or deprecated sun.* classes that either
cause a build failure or warnings.

I'm attaching a simple patch that makes more of those errors visible.

lwjgl 2.9.3 is a legacy release from 2015. It is the last version of the
2.x series and no longer supported. Upstream moved to lwjgl 3. If nobody
can fix this we should consider to remove lwjgl because the new version
3 would require new Kotlin build dependencies and more.
