An update that solves three vulnerabilities and has two security fixes can now
be installed.

## Description:

This update for java-21-openjdk fixes the following issues:

Security issues fixed:

  * CVE-2026-60589: OpenJDK: Improve Resource Resolving (bsc#1275777).
  * CVE-2026-61308: OpenJDK: Enhance HTTP Connections (bsc#1275778).
  * CVE-2026-70907: OpenJDK: Enhance TLS server (bsc#1275764).

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.
