Bug Fix(es):

• Additional validity checks in the handling of Zip64 files, JDK-8302483, were introduced in the 11.0.20 release of OpenJDK, causing the use of some valid zip files to now fail with an error. This release, 11.0.20.1, allows for zero-length headers and additional padding produced by some Zip64 creation tools. With both releases, the checks can be disabled using -Djdk.util.zip.disableZip64ExtraFieldValidation=true. (RHBZ#2237172)
• A maximum signature file size property, jdk.jar.maxSignatureFileSize, was introduced in the 11.0.20 release of OpenJDK by JDK-8300596, with a default of 8 MB. This default proved to be too small for some JAR files. This release, 11.0.20.1, increases it to 16 MB.
• The serviceability agent would print an exception when encountering null addresses while producing thread dumps. These null values are now handled appropriately. (JDK-8243210, RHEL-2761)
• The /usr/bin/jfr alternative is now owned by the java-11-openjdk package (RHEL-13557)
• The jcmd tool is now provided by the java-11-openjdk-headless package, rather than java-11-openjdk-devel, to make it more accessible (RHEL-13564)
