Comment (by breun):

 I wouldn't know how to troubleshoot this, but OpenJDK has only a few
 [https://wiki.openjdk.org/display/Build/Supported+Build+Platforms
 supported build platforms], so it's very possible that it won't work on
 these older OS versions.

 If you can't build OpenJDK from source, I would recommend installing a
 prebuilt binary OpenJDK distribution like Azul Zulu (`openjdk21-zulu`),
 Eclipse Temurin (`openjdk21-temurin`), Amazon Corretto
 (`openjdk21-corretto`), SapMachine (`openjdk21-sap`) or Microsoft OpenJDK
 (`openjdk21-microsoft`).
