Public bug reported: While building the April 2025 OpenJDK security updates, various JTREG (regression) tests that use zlib have failed. The failures are consistent and most probably related to hardware-accelerated compression using zEDC on s390x.
The following failures have been observed with openjdk-* packages: FAILED: java/util/zip/ZipFile/CopyJar.java FAILED: java/util/zip/CloseInflaterDeflaterTest.java FAILED: tools/pack200/PackTestZip64.java FAILED: tools/jmod/hashes/HashesTest.java FAILED: sun/security/tools/jarsigner/PreserveRawManifestEntryAndDigest.java FAILED: java/util/zip/DeInflate.java FAILED: java/util/zip/CloseInflaterDeflaterTest.java FAILED: tools/jlink/JLinkReproducibleTest.java FAILED: java/util/zip/CloseInflaterDeflaterTest.java FAILED: tools/jlink/JLinkReproducibleTest.java FAILED: tools/jar/modularJar/JarToolModuleDescriptorReproducibilityTest.java I confirm that all of these tests pass with environment variable DFLTCC=0, which disables hardware-accelerated compression. This in turn points to an issue with hardware-acceleration on s390x. Last month, I noted a similar failure in the Java's TCK test-suite [1].
