See comment here: https://github.com/openjdk/jdk/pull/28366#discussion_r2781992992 The old test did run with explicit uncompressed class pointers. I want to reuse the test, so I had to fix it to be able to run with compressed class pointers. With -UCCP, array headers for object arrays are 24 bytes; for +UCCP, array headers are 16 byte. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/28366#discussion_r2786317490
