There is an existing failing `test/jdk/java/lang/annotation/AnnotationType/AnnotationTypeRuntimeAssumptionTest.java` test - probably I should modify the fix to only skip the `Retention.RUNTIME` check when the `-XX:+PreserveAllAnnotations` option is on. Suggestions how to properly check value of `-XX:+PreserveAllAnnotations` from `sun/reflect/annotation/AnnotationParser.java ` welcomed. ------------- PR: https://git.openjdk.java.net/jdk/pull/4245
