Non security issue fixed: - java-21-openjdk classlist depends on the CPU count of the build machine (bsc#1221224). Changes for java-21-openjdk: - Update to jdk-21.0.12.1+1 (August 2026 CSPU) + backport upcoming upgrade of timezone data (bsc#1275035) + Explicitly use G1 if the JVM supports it. GC ergonomics pick SerialGC on single-CPU machines. SerialGC does not support dumping of the shared heap, thus the classlist is different on a single-CPU builder.
