This feels like a win-win if folks move from OpenJDK 8 and 11 to 17, 20, and beyond.

Any immediate downsides? (Of course, best thing to do is measure it.)

You mean Graal AOT?

For one thing, it doesn't support many features, like reflection.

For another, its slower than Java JIT after the warm up period.

Graal AOT is for small programs that need to start up and warm up fast, and consume as little memory as possible. But JIT is better for big, long running apps.

However, GraalVM JIT is also faster than OpenJDK.

Thank-you. Reflection and web services (long-lived) are pretty big ones, the former for annotations, aspects, and mutation testing.

(Assuming one or more of those use reflection.)

FINALLY

Maybe Minecraft will switch to GraalVM now... With some interesting moddability and performance implications.

I personally have seen some dev interest in GraalVM compiler development. But it instantly gets sapped away once the devs find out compiler contributions get sucked up into Enterprise Edition.
