This week’s Java roundup for December 19th, 2022 features news from OpenJDK, JDK 20, JDK 21, Spring Cloud 2022.0.0, point releases for other Spring projects, Open Liberty 22.0.0.13, Quarkus 2.15.1, Micronaut 3.7.5, Helidon 3.1.0, Hibernate 6.2.CR1, Eclipse Vert.x 4.3.7, point releases for Groovy, Camel 3.20, MicroStream joins Eclipse, Kotlin 1.8-RC2, and introducing SourceBuddy, Jarviz and Just.

OpenJDK

Ioi Lam, consulting member of technical staff at Oracle, has proposed improved support for archived Java heap objects in class data sharing (CDS) because Project Leyden will, more-than-likely, make extensive use of archived Java heap objects.

Due to a number of defined limitations in the G1, SerialGC and ParallelGC garbage collection algorithms related to CDS, the goals in this proposal are: uniform support of CDS for all collectors; and minimize the code needed for each collector to support CDS.

Recently submitted and subsequently updated issues already related to proposal are:

InfoQ will monitor progress on this proposal.

JDK 20

Build 29 of the JDK 20 early-access builds was made available this past week, featuring updates from Build 28 that include fixes to various issues. More details on this build may be found in the release notes.

JDK 21

Build 3 of the JDK 21 early-access builds was also made available this past week featuring updates from Build 2 that include fixes to various issues.

For JDK 20 and JDK 21, developers are encouraged to report bugs via the Java Bug Database.

The release of Spring for GraphQL 1.1.1 ships with new features such as: new builder customizers to customize the QuerydslDataFetcher and QueryByExampleDataFetcher repository classes by allowing these repositories to implement customizer interfaces; and relaxing the generic type check in @Argument Map as it was determined that this was too strict. There were also dependency upgrades to: Micrometer 1.10.2, Reactor 2022.0.1, Spring Framework 6.0.3 and Spring Security 6.0.1. Further details on this release may be found in the release notes.

Spring Modulith 0.2 has been released that delivers: a new @ApplicationModuleListener annotation to ease the declaration of asynchronous, transactional event listeners that run in a transaction; the application module dependency structure is now also exposed as Spring Boot actuator; and the Postgres event publication registry schema now follows Postgres best practices. More details on this release may be found in the release notes.

Open Liberty

IBM has released Open Liberty 22.0.0.13 featuring: the ability to configure the maximum age of their First Failure Data Capture (FFDC) application data collection system; and fixes for CVE-2022-3509 and CVE-2022-3171, both of which have parsing issues with text data and binary data, respectively, in the Protocol Buffers Java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 that can lead to a denial of service attack.

Quarkus

Red Hat has released Quarkus 2.15.1.Final that ships with bug fixes, improvements in documentation and dependency upgrades to Vert.x 4.3.6, Infinispan 14.0.3.Final, Dekorate 3.1.3 and mongo-client.version 4.8.1. Further details on this release may be found in the changelog.

Micronaut

The Micronaut Foundation has released Micronaut 3.7.5 featuring bug fixes and improvements such as: a change in the resulting Health status output from “Health monitor failed check with status {}” to “Health monitor check with status {}” since Health status only reports UP or DOWN; and an instance of the TextStreamCodec class now requires a bean of type ByteBufferFactory to fix a loading issue. More details on this release may be found in the release notes.

Helidon

Oracle has released Helidon 3.1.0 featuring: new Exponential and Fibonacci strategies defined in the Retry interface; support for the MicroProfile Config specification via a new MPConfigSourceProvider interface; a new relativeUris property in the OidcConfig class to allow an OIDC web client to use a relative path on the request URI; and dependency upgrades such as GraalVM 22.3.0, Netty 4.1.86.Final and PostgreSQL JDBC driver 42.4.3.

Hibernate

The first release candidate of Hibernate ORM 6.2 provides: support for Java records, mapping composite/struct types, and the Jakarta Persistence 3.1 specification; UUID support for MariaDB 10.7 and SQL Server 2008; allow the @SqlInsert, @SqlUpdate, @SqlDelete annotations to refer to a SecondaryTable class; and a new @PartitionKey annotation to identify a field of an entity that holds the partition key of a table.

In response to a number of reported bugs found in version 4.3.6, Eclipse Vert.x 4.3.7 has been released featuring a dependency upgrade to Netty 4.1.86 to address CVE-2022-41881, HAProxyMessageDecoder Stack Exhaustion DoS, and CVE-2022-41915, HTTP Response Splitting from Assigning Header Value Iterator. Further details on this release may be found in the release notes.

Apache Software Foundation

A maintenance release of Apache Groovy 3.0.14 features bug fixes, dependency upgrades and two improvements: the static type checker does not recognize closure input parameter when implementing an interface with a map; and the evaluateExpression() method defined in the StaticTypeCheckingSupport class can now provide lightweight evaluation for simple expressions. More details on this release may be found in the release notes.

Apache Groovy 2.5.20, also a maintenance release, features bug fixes, dependency upgrades and the same type checker improvement as described in version 3.0.14. Further details on this release may be found in the release notes.

The release of Apache Camel 3.20.0 delivers over 200 bug fixes, improvements, dependency upgrades and new features such as: provide completion for positional file path parameters (camel-jbang component); added support for Event Resources (camel-kubernetes component); provide a prefixId to the route model such that generated IDs of the route is prefixed (camel-core component); and a new camel-etcd component. More details on this release may be found in the release notes.

MicroStream

MicroStream has announced that they have joined the Eclipse Foundation as a member. With MicroStream already integrated with Helidon and Micronaut, their goal is to closely collaborate with the Eclipse community and actively contribute to Eclipse projects. InfoQ will follow up with a more detailed news story.

Kotlin

The second releases candidate of Kotlin 1.8.0 delivers fixes such as: an IllegalStateException upon reading a class that delegates to a Java class with a definitely non-nullable type with a flexible upper bound; an argument for the UseSerializers class does not implement an instance of the KSerializer interface or does not provide serializer for a concrete type; and no mapping for symbol, VALUE_PARAMETER SCRIPT_IMPLICIT_RECEIVER, on the JVM IR backend.

SourceBuddy

SourceBuddy, a new utility that compiles Java source code dynamically created in a Java application, was introduced by Peter Verhas, architect at EPAM Systems, this past week and has also quickly released version 2.0 featuring: a major restructuring of the class loading structure; hidden and non-hidden classes may now be mixed; and removal of the loadHidden() method in favor of the hidden() method for each added source separately. As the latter feature is a breaking change, it was necessary to provide a major release within the short timeframe. InfoQ will follow up with a more detailed news story.

Jarviz

Jarviz, a new JAR file analyzer utility, has been introduced by Andres Almiray to the Java community. Version 0.1.0 delivers: GAV support to resolve JARs; streamline manifest commands; and resolve the output directory before invoking URL-based processors. Further details on this release may be found in the release notes and InfoQ will follow up with a more detailed news story.

Just

Just, a command Line toolkit for developing Spring Boot applications, was introduced by Maciej Walkowiak, freelance architect & developer, earlier this month. Version 0.12.0, released this past week, features: a significant improvement to the just kill command such that it stops/kills a running Docker container, instead of killing the Docker process, when it learns that there is a Docker container running on a chosen port; two new configuration properties, just.build.extra-args and just.build.maven.profiles, for the just build command to simplify the build configuration; and the value, SPRING_BOOT, can be set to the just.framework property if the framework autodetection fails. InfoQ will follow up with a more detailed news story.
