`Exception in thread "main" java.lang.NoClassDefFoundError: dagger/internal/Preconditions` with JDK 20 and 21

Hello,

When using rules_kotlin (tip) with JDK 21 and 20, I see this error:

ERROR: <foo>/lab/lang/kt/BUILD.bazel:140:12: KotlinCompile //lab/lang/kt:types_test_kt_ { kt: 1, java: 0, srcjars: 0 } for darwin_arm64 failed: Worker process did not return a WorkResponse:

This error does not occur with JDK 17. Not sure why that is the case though.

This seems to be "fixed" by removing the shade on rule dagger.** io.bazel.kotlin.builder.dagger.@1, though eventually the issue downstream re-appears that I imagine inspired that jarjar rule.
