I came across https://bugs.launchpad.net/ubuntu/+source/zlib/+bug/1990379 which reported the same issue. However, it claimed to have fixed this issue in 1:1.2.11.dfsg-2ubuntu9.2.
** Description changed: - I have been observing this failure on jammy/s390x PS6 VMs off late, - while running OpenJDK TCK certification tests.
