Re: JDK 20 Rampdown Phase 1 & Valhalla LW4 Early-Access builds
David, we have one problem with our tests: See here: https://ci-hadoop.apache.org/view/ZooKeeper/job/ZooKeeper-Java-EA/82/testReport/junit/org.apache.zookeeper.test/StaticHostProviderTest/testEmptyResolution/ The error is (even with latest Mockito): Cannot mock/spy class java.net.InetAddress Mockito cannot mock/spy because : - sealed class My understanding is that we have to change our tests and stop mocking InetAddress, correct ?

JDK 20 Rampdown Phase 1 & Valhalla LW4 Early-Access builds
Welcome to the final OpenJDK Quality Outreach update for 2022! JDK 20, scheduled for General Availability on March 21 2023, is now in Rampdown Phase One (RDP1) [1]. At this point, the overall JDK 20 [2] feature set is frozen (see below the final list of JEPs integrated into JDK 20) and only low-risk enhancements might still be considered. The coming weeks should be used to identify and resolve as many issues as possible, i.e. before JDK 20 enters the Release Candidates phase in early February 2023. ## JDK 20 Early-Access builds The latest Early-Access (builds 27) are available [2] with the Release Notes here [3]. Those builds are provided under the GNU GPL v2, with the Classpath Exception. ### JEPs integrated into JDK 20: JEP 429: Scoped Values (Incubator) JEP 432: Record Patterns (2nd Preview) JEP 433: Pattern Matching for switch (4th Preview) JEP 434: Foreign Function & Memory API (2nd Preview) JEP 436: Virtual Threads (2nd Preview) JEP 437: Structured Concurrency (2nd Incubator) [1] https://mail.openjdk.org/pipermail/jdk-dev/2022-December/007233.html [2] https://jdk.java.net/20/ [3] https://jdk.java.net/20/release-notes ### Changes in recent JDK 20 builds that may be of interest: Build 27: - JDK-8297794: Deprecate JMX Management Applets for Removal - JDK-8297118: Change IncompatibleClassChangeError to MatchException for exhaustive switch statements and switch expressions - JDK-8294047: HttpResponseInputStream swallows interrupts - JDK-8281236: (D)TLS key exchange named groups - JDK-8280798: com.sun.jdi.ObjectReference::setValue spec should prohibit any final field modification - JDK-8295350: JFR: Add stop methods for recording streams - JDK-8295044: Implementation of Foreign Function and Memory API (2nd Preview) - JDK-8296896: Change virtual Thread.yield to use external submit - JDK-8297804: (tz) Update Timezone Data to 2022g - JDK-8295803: Console should be usable in jshell and other environments - JDK-828: Implementation of Scoped Values (Incubator) - JDK-8296672: Implementation of Virtual Threads (2nd Preview) Build 26: - JDK-8297276: Remove thread text from Subject.current - JDK-8297030: Reduce Default Keep-Alive Timeout Value for httpclient - JDK-8247645: ChaCha20 Intrinsics Build 25: - JDK-8296472: Remove ObjectLocker around appendToClassPathForInstrumentation call - JDK-8290313: Produce warning when user specified java.io.tmpdir directory doesn't exist - JDK-8288717: Add a means to close idle connections in HTTP/2 connection pool - JDK-8288047: Accelerate Poly1305 on x86_64 using AVX512 instructions - JDK-8059632: Method reference compilation uses incorrect qualifying type - JDK-8297161: Add additional Service Attributes to Standard Algorithm Names guide - JDK-8294073: Performance improvement for message digest implementations Build 24: - JDK-8294731: Improve multiplicative inverse for secp256r1 implementation - JDK-8296715: CLDR v42 update for tzdata 2022f - JDK-8296958: [JVMCI] add API for retrieving ConstantValue attributes Build 23: - JDK-8296226: Add constructors (String,Throwable) and (Throwable) to InvalidParameterException - JDK-8295673: Deprecate and disable legacy parallel class loading workaround for non-parallel-capable class loaders - JDK-8294241: Deprecate URL public constructors - JDK-8289689: (fs) Re-examine the need for normalization to Unicode Normalization Format D (macOS) - JDK-8279164: Disable TLS_ECDH_* cipher suites - JDK-8178355: IdentityHashMap uses identity-based comparison for values everywhere except remove(K,V) and replace(K,V,V) - JDK-8296108: (tz) Update Timezone Data to 2022f ## Heads-up - JDK 21: First Early-Access Builds When JDK 20 entered RDP1 [4], the JDK mainline [5] was (a) forked into a JDK 20 stabilization repository [6], and (b) set to JDK 21. As a consequence, the first JDK 21 Early-Access builds have been published [7].

For additional details on those EA builds, make sure to read these LW4 release notes [10].
