This week’s Java roundup for September 1st, 2025, features news highlighting: JEP 517 proposed to target for JDK 26; TornadoVM releases GPULlama3.java 0.2.0; the September 2025 edition of the Payara Platform; point releases of Quarkus, Micronaut, Apache Kafka and Apache Tomcat; and second release candidates of Grails 7.0 and Gradle 9.1.
OpenJDK
JEP 517, HTTP/3 for the HTTP Client API, has been elevated from Candidate to Proposed to Target for JDK 26. This JEP proposes to “update the HTTPClient API to support the HTTP/3 protocol, so that libraries and applications can interact with HTTP/3 servers with minimal code change.” The review is expected to conclude on September 10, 2025.
JDK 25
Build 36 remains the current build in the JDK 25 early-access builds. Further details on this release may be found in the release notes.
JDK 26
Build 14 of the JDK 26 early-access builds was made available this past week featuring updates from Build 13 that include fixes for various issues. More details on this release may be found in the release notes.
Payara
Payara has released their September 2025 edition of the Payara Platform that includes Community Edition 6.2025.9, Enterprise Edition 6.30.0 and Enterprise Edition 5.79.0. Along with component upgrades, all three editions deliver: a new feature that reduces the logging level from INFO to FINE for the “Clustered CDI Event bus initialized” log entry; a resolution to the alternatedocroot_n property in the payara-web.xml file not working in Payara Micro; and prevention of a race condition if a resource adaptor wasn’t deployed by the time the Java Transaction Service recovery thread was ready to use it.
This edition also delivers Payara 7.2025.1.Beta1 that advances support for Jakarta EE 11 and includes support for Docker JDK 21.0.8. Further details on these releases may be found in the release notes for Community Edition 6.2025.9 and Enterprise Edition 6.30.0 and Enterprise Edition 5.79.0.
Quarkus
Quarkus 3.26.2, the second maintenance release, ships with notable changes such as: ensure that the setup() method, defined in the NativeImageBuildContainerRunner class, is only invoked once when using the Quarkus AWT extension; and improvements to the HibernatePropertiesTest class that replaces use of JUnit 5 with AssertJ and improved failure messages. More details on this release may be found in the release notes.
The Quarkus team also released version 0.3.0.Alpha1 of the A2A Java SDK that aligns with the Agent-to-Agent (A2A) specification. New features include: support for the gRPC and JSON-RPC transport protocols; and the ability to declare supported transport protocols via the AgentCard record. Further details on this release may be found in the release notes.
Micronaut
The Micronaut Foundation has released version 4.9.3 of the Micronaut Framework, based on Micronaut Core 4.9.10, features bug fixes and patch updates to modules: Micronaut for Spring and Micronaut Data. New classes, InterceptorPrivate1Spec, InterceptorPrivate2Spec and InterceptorPrivate3Spec, were created to resolve non-accessible interceptors. More details on this release may be found in the release notes.
TornadoVM
The TornadoVM team has released version 0.2.0 of the GPULlama3.java project, an open-source GPU-accelerated Llama 3 inference powered by TornadoVM. New features include: support for WindowsOS; a refactor of the TornadoVMMasterPlan class that centralizes the scheduler selection logic and removes the external isNvidia parameter; and support for new models using the GPT-Generated Unified Format (GGUF). These include: Mistral AI; Qwen AI; DeepSeek-R1-Distill-Qwen-1.5B; and Phi-3. Further details on this release may be found in the release notes.
Apache Software Foundation
The release of Apache Kafka 4.1.0 delivers bug fixes and new features such as: the AlterPartitionReassignments API (consisting of the AlterPartitionReassignmentsOptions class and associated JSON files) now allows callers to specify an option to preserve the replication factor and avoid a potential race condition; and a refactoring of the TransactionManager class that removes the use of the Java ThreadLocal class in favor of using the application and Sender threads to maintain the desired behavior. More details on this release may be found in the release notes.
The release of Apache Tomcat 11.0.11 ships with notable changes such as: a resolution to sessions lost from concurrent use of the save() and remove() methods, defined in the FileStore class, when used with an instance of the PersistentValue class; and a refactor of the WebResource interface to use the new KeyedReentrantReadWriteLock class for improved locking. Further details on this release may be found in the release notes.
The second release candidate of Apache Grails 7.0.0 provides bug fixes and new features such as: hide the ability to select the servlet features in favor of using the --servlet command line option as the former does not properly override the ServletImpl enum class. More details on this release may be found in the release notes.
Gradle
The second release candidate of Gradle 9.1.0 featuring: support for the upcoming GA release of JDK 25; improvements to their diagnostics and preview tools that includes a new task graph to visualize dependencies without having to build the application and enhanced project reporting; and an enhanced command-line interface for improved usability and feedback in the terminal. Further details on this release may be found in the release notes.
