This week’s Java roundup for October 6th, 2025, features news highlighting: milestone releases of Jakarta Query 1.0, Spring AI 1.1 and Spring Batch 6.0; the October 2025 edition of Open Liberty; point releases of Quarkus, Apache Camel and JetBrains Ktor.
OpenJDK
Version 8.1.0 of the Regression Test Harness for the JDK, jtreg, has been released and ready for integration in the JDK. The most significant changes are: improvements in the logging format and order relative to agents, actions and test-related execution points; and the XAUTHORITY environment variable is now preserved when launching tests on Unix-like platforms. More details on this release may be found in the release notes.
JDK 26
Build 19 of the JDK 26 early-access builds was made available this past week featuring updates from Build 18 that include fixes for various issues. More details on this release may be found in the release notes.
For JDK 26, developers are encouraged to report bugs via the Java Bug Database.
Jakarta EE
The first milestone release of Jakarta Query 1.0 delivers notable changes such as: a unification of the Jakarta Persistence Query Language (JPQL) and Jakarta Data Query Language (JDQL) definitions into a single document; the introduction of a new, self-contained definition of the language semantics; and a generalization of the query language that may consider client programming from other languages.
The ballot to include Jakarta Query into the Jakarta EE 12 Platform and Web Profile, initiated on September 29, 2025, is scheduled to conclude on October 13, 2025. So far, votes from the platform development team and the Java community have all been positive.
Further details on this release may be found in the release notes and this milestone specification document.
Spring Framework
The third milestone release of Spring AI 1.1.0 ships with bug fixes, improvements in documentation, dependency upgrades and a focus on enhancements to the Model Context Protocol (MCP). In particular, there was an upgrade to MCP Java SDK 0.14.0; and new integrations such as: chat memory with Azure Cosmos DB; and metadata filtering with GemFire.
The fourth milestone release of Spring Batch 6.0.0 provides bug fixes and new features such as: all APIs are now annotated with JSpecify; and the ability to configure Mongo sequence incrementers in the MongoJobRepositoryFactoryBean class. There was also a replacement on use of the Micrometer global static MeterRegistry abstract class with the more configurable ObservationRegistry interface as the former was difficult to customize. More details on this release may be found in the release notes.
Open Liberty
The release of Open Liberty 25.0.0.10 features: support for JDK 25; and a new overrideLibraryRef attribute for the <classloader> element in the server.xml file that allows for the library class path to be searched before the application class path to override classes that are already included in the application. There was also a resolution to CVE-2020-36732, an exposure in which the Node.js crypto-js package, a JavaScript library of cryptography standards, before version 3.2.1, generated random numbers by concatenating the string “0.” with an integer, yielding an output that is more predictable than necessary.
Quarkus
Quarkus 3.28.3, the third maintenance release, ships with bug fixes, dependency upgrades and notable changes such as: OIDC client requests, marked under the quarkus-oidc-client property, are now logged in DEBUG mode; and ensure a call to the reset() method, defined in the Vert.x HttpServerResponse interface, if an exception occurs while streaming a response so that clients can detect the error. Further details on this release may be found in the release notes.
Apache Camel
The release of Apache Camel 4.15.0 delivers bug fixes, dependency upgrades and new features such as: a new Camel-Keycloak extension to support running operations on Keycloak instance and policy enforcements; a new Camel-Docling extension for converting and processing documents using the IBM Docling AI document parser; and support for Micrometer in the Camel-Resilience4j extension. More details on this release may be found in the release notes.
Grails
The Apache Software Foundation (ASF) has announced that the Apache Grails project, donated to the foundation in June 2025, has graduated from an Incubating project to a Top-Level project. Once maintained under the Grails Foundation and Object Computing, the process to ultimately donate Grails was initiated in May 2024 with this open letter by Gina Bremehr, CEO at Object Computing, describing a “marked decline in enterprise adoption and commercial investment” in Grails. The project was donated in June 2025.
The fourth milestone release of Grails 7.0.0, delivered in June 2025, was the first release under the auspices of the ASF. The second release candidate of Grails 7.0.0, released in September 2025, is the current version. The GA release is scheduled to be available in mid-October 2025.
JetBrains Ktor
The release of Ktor 3.3.1, the asynchronous framework for creating microservices and web applications, features notable changes such as: an update to Kotlin 2.2.20; a resolution to a NumberFormatException upon processing an HTTP header with the Content-Length value set to null; and a resolution to an instance of the ClientSSESession class not behaving as intended with the design of the CoroutineScope interface. Further details on this release may be found in the release notes.
