jdk20 in eclipse and Scoped values

[Kasper Nielsen]

Hi,

If you want proper Java 20 support from the Eclipse compiler.
You will have to wait on a preview patch via Marketplace.
or wait for Eclipse 23-06 to have full support for Java 20.

However, you should be able to use ScopedValue without the patch.
Make sure you have disabled "enable preview features for Java 19"
for the compiler. And set the compliance level to 19. I'm running
vanilla 2022-12 without any issues.
