GraalVM is genuinely great -- Native Image and the polyglot story are impressive.

I was put off by the earlier licensing - it was confusing, which wasn't great in a license. The GraalVM Free Terms and Conditions "GFTC" now seems better (curious if people agree?), but I wonder if it came too late.

The decoupling from Java SE was good in many ways, but it also made the future a little less clear too.
