Do you mean to represent the filler array as `FillerElement[]`, with 1 element per underlying int, and that element is null? Object array elements are not always 4 bytes, so that adds a bit of extra messiness - do we factor that in during the dump (for 8-byte oops, emit half the elements so the size looks right?) or leave it to the analyzer (filler array refs are always int-sized)? ------------- PR Comment: https://git.openjdk.org/jdk/pull/32542#issuecomment-5492535797
