no action required from language pov
from eclipse.jdt.core.
I disagree that nothing needs to be done.
I have enabled language level 21 and preview-features:
However, usage of ScopedValue
is not possible in Eclipse:

Have you configured the JRE in Eclipse to be Java 21? The ScopedValue class itself is added in Java 21 so this is a prereq.

If you mean the default in "Installed JREs" also yes - how could I have set the "Compiler compliance level" to 21 as you can see in my earlier screenshot. Also all projects are using the default JRE. There is not other Java JDK/JRE involved at all.
