This week's Java roundup for May 29th, 2023, features news from OpenJDK, JDK 21, GlassFish 7.0.5, Payara, Open Liberty 23.0.0.5, IBM Semeru Runtimes, Micronaut 4.0-M6, Quarkus 3.1, Hibernate ORM 6.2.4, Hibernate Reactive 2.0, Hibernate Search 6.2.Beta1, Camel Quarkus 3.0-M2, Camel 3.14.8, Tomcat Native 2.0.4 and 1.2.37, Ktor 2.3.1, Multik 0.2.2, JobRunr 6.2.1, JDKMon 17.0.63 and Gradle 8.2-RC1.

JEP 452, Key Encapsulation Mechanism API, has been promoted from Proposed to Target to Targeted for JDK 21. This feature JEP type proposes to: satisfy implementations of standard Key Encapsulation Mechanism (KEM) algorithms; satisfy use cases of KEM by higher level security protocols; and allow service providers to plug-in Java or native implementations of KEM algorithms. This JEP was recently updated to include a major change that eliminates the DerivedKeyParameterSpec class in favor of placing fields in the argument list of the encapsulate(int from, int to, String algorithm) method. InfoQ will follow up with a more detailed news story.

JEP 451, Prepare to Disallow the Dynamic Loading of Agents, has been promoted from Proposed to Target to Targeted for JDK 21. Originally known as Disallow the Dynamic Loading of Agents by Default, and following the approach of JEP Draft 8305968, Integrity and Strong Encapsulation, this JEP has evolved from its original intent to disallow the dynamic loading of agents into a running JVM by default to issue warnings when agents are dynamically loaded into a running JVM. Goals of this JEP include: reassess the balance between serviceability and integrity; and ensure that a majority of tools, which do not need to dynamically load agents, are unaffected.

JEP 453, Structured Concurrency (Preview), has been promoted from Candidate to Proposed to Target for JDK 21. Formerly a incubating API, this initial preview incorporates enhancements in response to feedback from the previous two rounds of incubation: JEP 428, Structured Concurrency (Incubator), delivered in JDK 19; and JEP 437, Structured Concurrency (Second Incubator), delivered in JDK 20. The only significant change features the fork() method, defined in the StructuredTaskScope class, returns an instance of TaskHandle rather than a Future since the get() method in the TaskHandle interface was restructured to behave the same as the resultNow() method in the Future interface. The review is expected to conclude on June 6, 2023.

JEP 446, Scoped Values (Preview), has been promoted from Candidate to Proposed to Target for JDK 21. Formerly known as Extent-Local Variables (Incubator), this JEP is now a preview feature following JEP 429, Scoped Values (Incubator), delivered in JDK 20. This JEP proposes to enable sharing of immutable data within and across threads. This is preferred to thread-local variables, especially when using large numbers of virtual threads. The review is expected to conclude on June 6, 2023.

Build 25 of the JDK 21 early-access builds was also made available this past week featuring updates from Build 24 that include fixes to various issues. Further details on this build may be found in the release notes.

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

GlassFish 7.0.5, the fifth maintenance release, delivers a new feature that asynchronously updates the instance status in the Admin Console. Notable bug fixes include: deployment-time recursive bytecode preprocessing in the WebappClassLoader class; the JMX server accepting an arbitrary object as credentials; and a validation error upon deploying an application to a cluster. More details on this release may be found in the release notes.

Payara has been authorized by the Common Vulnerabilities and Exposures (CVE) Program as a CVE Numbering Authority (CNA). Payara is now allowed to publish authoritative cybersecurity vulnerability information about its products via the CVE Program.

Discussing how Payara can better support their customers, Fabio Turizo, service manager and senior engineer at Payara, stated:

Becoming a CVE Numbering Authority creates an extra level of dependability for those using our products and continues our commitment in adhering to and maintaining the best possible security standards. A key benefit is peace of mind when developing your mission critical Jakarta EE applications. As a CVE Numbering Authority, we ensure that when problems do occur, they can be quickly identified and a solution found, with ease of communication and total transparency.

The CVE Program is sponsored by the Cybersecurity and Infrastructure Security Agency of the U.S. Department of Homeland Security. Payara joins organizations such as The Apache Software Foundation, VMware, Oracle and IBM as defined in the CNA list of partners.

IBM has released Open Liberty 23.0.0.5 featuring updates to 44 of the Open Liberty Guides that now support MicroProfile 6 and Jakarta EE 10. These include: Consuming a RESTful Web Service; Accessing and Persisting Data in Microservices using Java Persistence API (JPA); and Deploying a Microservice to Kubernetes using Open Liberty Operator. There were also notable bug fixes such as: a memory Leak found in the SchemaRegistry class within the MicroProfile Open API specification; and an EntryNotFoundException when defining a non-identifier type property for the input/output mapping of federated registries.

IBM has also released versions 19.0.2, 17.0.7, 11.0.19 and 8.0.372 of their Semeru Runtime, Open Edition, as part of their quarterly update. Further details on this release may be found in the release notes.
