The error still occurs on the same s390x virtual machine with QEMU
version 6.1.
After building QEMU 6.1, I started the virtual machine as follows:
$ ../qemu-6.1.0/build/s390x-softmmu/qemu-system-s390x \
-m 2048 -drive if=virtio,file=s390x-focal.qcow2,cache=none
The QEMU 6.1.0 monitor shows:
(qemu) info version
6.1.0
On the guest, I installed the new 'openjdk-17-jre-headless' OpenJDK 17
package in Ubuntu 20.04. Although the installation fails because of this
bug, the 'java' command is available after the attempt to install the
package.
$ sudo apt-get install openjdk-17-jre-headless
The error in this bug report still occurs:
$ /usr/lib/jvm/java-17-openjdk-s390x/bin/java --version
#

I'll also attach the corresponding log file.
For reference, the guest shows the following CPU information under QEMU
6.1.
