Java News Roundup: LibericaJDK with RISC-V, Payara Platform, Gradle 8.6, LangChain4j, Spring Cloud


This week's Java roundup for January 29th, 2024, features news highlighting: LibericaJDK 21 with support for RISC-V, January release of Payara Platform, Gradle 8.6, LangChain4j 0.26, GraalVM Native Build Tools 0.10, and multiple releases of Open Liberty and Eclipse Vert.x.


Brian Goetz, Java Language Architect at Oracle, has submitted JEP Draft 8324965, Class-File API (Second Preview), for a second round of preview to obtain feedback from the previous round of preview: JEP 457, Class-File API (Preview), to be delivered in the upcoming release of JDK 22. This JEP proposes to provide an API for parsing, generating, and transforming Java class files. This will initially serve as an internal replacement for ASM, the Java bytecode manipulation and analysis framework, in the JDK with plans to have it opened as a public API. Goetz has characterized ASM as "an old codebase with plenty of legacy baggage" and provided background information on how this draft will evolve and ultimately replace ASM.

BellSoft has released Liberica JDK 21, their downstream distribution of OpenJDK, with support for the RISC-V architecture due to its increasing popularity in embedded systems. BellSoft states key reasons for choosing Java as a suitable language for RISC-V:

  • High performance and small memory footprint, especially when using their Liberica JDK for Embedded Systems.
  • Great portability with Java's write once, run anywhere model that eliminates the need to rewrite an application when introducing a new architecture in production.
  • Numerous standard libraries for any task keep the developers from writing their implementation for a particular use case.
  • Convenient in-built memory management to avoid memory allocation errors.

Further details on BellSoft's assessment on RISC-V's rapid expansion and Java may be found in this article.


The release of Hibernate ORM 6.4.3.Final delivers bug fixes and a new feature that supports Oracle GraalVM for builds using Atlas, a modern tool for managing database schemas. More details on this release may be found in the release notes.
