Important: java-21-openjdk security update

The OpenJDK 21 packages provide the OpenJDK 21 Java Runtime Environment and the OpenJDK 21 Java Software Development Kit. Security Fix(es): * JDK: Enhance crypto algorithm support (CVE-2026-22007) * JDK: Improve Kerberos credentialing (CVE-2026-22013) * JDK: Enhance Path Factories Redux (CVE-2026-22016) * JDK: Enhance Zip file reading (CVE-2026-22018) * JDK: Enhance certificate chain validation (CVE-2026-22021) * JDK: Updating FreeType 2.14.1 (CVE-2026-23865) * JDK: Enhance TLS connection handling (CVE-2026-34282) * JDK: Enhance key generation (CVE-2026-34268) Bug Fix(es): * When copying files, OpenJDK 21 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 21 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release.
