The main motivation for this change is that
java.lang.annotation.Repeatable has a parameter for the container
annotation, which is lost during conversion to
kotlin.annotation.Repeatable. To support j.l.a.Repeatable in backend
properly, it's absolutely necessary to be able to load the container
annotation for any repeatable annotation class, so the original
j.l.a.Repeatable needs to be stored in the descriptor and accessible
from the backend.
Instead of mapping j.l.a.Repeatable -> k.a.Repeatable, add a frontend
service PlatformAnnotationFeaturesSupport that will determine if an
annotation is repeatable "according to the platform rules", which for
JVM means that it's annotated with j.l.a.Repeatable.
Some effects of this change include:
- Usages of j.l.a.Repeatable are no longer reported as "deprecated", the
corresponding test is deleted
- Usages of repeatable annotations declared in Java with non-SOURCE
retention with LV 1.5 and earlier will now result in a slightly
different error (REPEATED_ANNOTATION instead of
NON_SOURCE_REPEATED_ANNOTATION)
