This week's Java roundup for October 18th, 2021, features news from OpenJDK JEPs, Oracle's Releases Critical Patch Update for October 2021, JDK 18, numerous Spring Projects updates, Quakus 2.3.1, Payara Platform, Hibernate Search 6.0.7, GraalVM 21.3, Java for VS Code 1.0 and Apache Camel for VS Code 0.1.0. The program for the JakartaOne Livestream 2021 conference has been finalized.

OpenJDK

JEP 416, Reimplement Core Reflection with Method Handles, has been promoted from Candidate to Proposed to Target for JDK 18. This JEP proposes to reimplement the java.lang.reflect classes, Method, Constructor<T> and Field, on top of method handles defined in java.lang.invoke. These method handles will now serve as the mechanism for reflection to reduce the cost of maintenance and development of both packages. The review for JEP 416 concludes on October 26, 2021.

JEP 420, Pattern Matching for switch (Second Preview), has been promoted from Draft to Candidate status. This JEP allows a target switch expression to be tested against a number of patterns, each with a specific action, allowing complex data-oriented queries to be expressed concisely and safely. This is the second preview following JEP 406, Pattern Matching for switch (Preview), that was delivered in JDK 17. Enhancements include: an improvement in dominance checking that forces a constant case label to appear before a guarded pattern of the same type; and an exhaustiveness checking of the switch block is now more precise with sealed hierarchies.

Brian Goetz, Java language architect at Oracle, spoke to InfoQ in September 2017 when pattern matching was still in its proof-of-concept phase. Pattern matching for the instanceof operator, JEP 394, was delivered in JDK 16.

JDK 17

Update releases for JDK 17.0.1, 11.0.13, 8u311 and 7u321 have been made available as part of Oracle's Releases Critical Patch Update for October 2021. More details may be found in the release notes for JDK 17, JDK 11, JDK 8 and JDK 7.

JDK 18

Build 20 of the JDK 18 early-access builds was made available this past week, featuring updates from Build 19 that include fixes to various issues. More details may be found in the release notes.

The feature set for JDK 18 currently stands as follows:

Developers are encouraged to report bugs via the Java Bug Database.

Spring Boot 2.5.6 was released featuring 43 bug fixes, documentation improvements and dependency upgrades.

Spring Boot 2.4.12 was released featuring 36 bug fixes, documentation improvements and dependency upgrades.

On the road to Spring Boot 2.6.0, the first release candidate was made available featuring 85 bug fixes, documentation improvements and dependency upgrades. More details may be found in the release notes.

Spring Cloud 21.0.0-M3 is compatible with Spring Boot 2.6.0-M3.

Spring Data 2021.0.6 and 2020.0.14 were released featuring dependency upgrades and bug fixes for both versions that are built on top of Spring Framework 5.3.11. These versions may be consumed with Spring Boot 2.5.6 and 2.4.12, respectively.

On the road to Spring Data 2021.1, the first release candidate was made available providing notable changes such as: deprecating support for RxJava 2; a refined SQL DSL for Spring Data JDBC that accepts complex JOIN conditions and subselects; and support for exists and not empty keywords in Elasticsearch.

Spring Cloud Square 0.4.0-M2 was released featuring: support for configuring different WebClient.Builder beans for each instance of @RetrofitClient; and support for Spring Native related to non-load-balanced use-cases.

Payara

Payara has released their October 2021 edition of the Payara Platform. Community Edition 5.2021.8 features seven improvements and seven bug fixes. Enterprise Edition 5.32.0 features eight improvements and nine bug fixes. Both editions share a security fix in which an additional check is performed when using Client Certificate authentication to ensure that a certificate is valid, and five component upgrades such as Eclipse Mojarra 2.3.14, Apache Commons IO 2.11 and Hazelcast 4 which is a breaking change in the Enterprise Edition.

More details may be found in the release notes for the Community and Enterprise editions.
