Formerly known as Object Classes and Values (Preview), this JEP proposes to enhance the language with value objects, defined as objects that: only contain final fields; do not have identity; and are solely distinguished by the values of their respective fields.

More details on this release may be found in the release notes.

Apache TomEE

The release of Apache TomEE 10.2.0 delivers dependency upgrades and resolutions to notable bug fixes such as: the sslTruststorePassword parameter from the HttpConnection inner class, defined in the HttpConnectionFactory class, is not masked/stripped during logging; and an AuthenticationException thrown from within the authenticate() method, defined in the JNDIContext class that loses the cause thrown by the RemoteException. Further details on this release may be found in the release notes.

Java Operator SDK

The release of Java Operator SDK 5.5.0 ships with notable changes such as: a complete and consistent family of update/patch/create methods in the ResourceOperations class that support the RFC 6902, JavaScript Object Notation (JSON) Patch, and RFC 7386, JSON Merge Patch, specifications; and a new Matcher interface that allows developers to plug a custom matching strategy into the overloaded matchAndFilter() method defined in the Options class.

LangChain4j

The formal release (along with the twenty-eighth beta release) of LangChain4j 1.18.0 provides bug fixes and new features such as: a new Belief-Desire-Intention (BDI) agentic pattern that "provides a structured method to formalize psychological concepts for software and robotic systems;" a new TextToSpeechModel interface to support for the OpenAI Text-to-Speech API; and a new MistralAiBatchChatModel class to support the Mistral Batch API. Further details on this release may be found in the release notes.

Micronaut

The Micronaut Foundation has released version 5.0.5 of the Micronaut Framework, based on Micronaut Core 5.0.6, featuring patch updates to modules: Micronaut AWS, Micronaut gRPC, Micronaut Oracle Cloud, and Micronaut Logging. More details on this release may be found in the release notes.

Quarkus

Quarkus Shim, a new extension introduced by the Quarkus team, allows developers to add, wrap, or replace behavior in a Java class during a Quarkus build. As per the blog post,

The change happens during augmentation. There is no Java agent and no runtime instrumentation. The transformed class works in JVM mode, dev mode, and native executables.

This is an experimental extension built with Quarkus 3.37.3.

Oracle

Oracle has introduced a new AI-native builder experience for Oracle AI Agent Studio for Fusion Applications. This allows customers to create and natively run Fusion Agentic Applications from within Oracle Fusion Cloud Applications. This new builder experience provides "no-code, low-code, and pro-code development into one Fusion-native framework."

It is important to note that AI Agent Studio and Fusion Cloud Applications are subscription services.
