This for certain can be done if they are ready once a class is linked, and we should probably update unsafe's comment as well. Can you confirm that they staticFieldBase/Offset are safe to be called before initialization? If this change is safe, we can significantly reduce the initial-call overhead of the lazy VH significantly as well. ------------- PR Comment: https://git.openjdk.org/jdk/pull/13821#issuecomment-1572801392
