jdk20 in eclipse and Scoped values

[Davor Hrg]

thanks for the tips Kasper,

looks like I will have to wait for Eclipse 23-06 or a milestone with java
20 support before it.

I can not get eclipse to import ScopedValue.

Thanks again for the hints, being this close to the bleeding edge is not
for me :)
