Background
OpenSUSE switched from update-alternatives to libalternatives for openjdk
leaving the alternatives symbolic links out of picture for cmake to find.

-- Found Java: /usr/bin/java (found suitable version "21.0.11", minimum required is "1.6")

-- Could NOT find JNI (missing: JAVA_INCLUDE_PATH JAVA_INCLUDE_PATH2 AWT JVM) 

Even though openjdk-devel is installed in the build environment.

Resolution
Until CMake / OpenSUSE arrive at a conclusion, manually re-create the symbolic links in the container environment.
