New on Foojay: Alessandro Pignotti explains what's in CheerpJ 5.0.

The release adds Java 21 and 25 support, ships the full JDK so javac and jshell run client-side, and includes an experimental WasmGC engine. Stabilizing that engine is planned for CheerpJ 6.0 in early 2027.

☕ OpenLDK: Bringing the Java World into Common Lisp

｢ OpenLDK is a JIT compiler and runtime for Java, written in Common Lisp. It reads Java bytecode, translates it into Lisp, and lets SBCL compile that Lisp into native machine code. Java objects live in the same process and heap as the Lisp application.
My goal is to make Java libraries feel at home in Common Lisp. For general Java execution, HotSpot will be much faster ｣

@frankdelporte explains how Sheetmusic4J 0.0.5 adds LilyPond import and export. A .ly file can now be loaded and rendered natively in JavaFX without running LilyPond, and any score can be saved as LilyPond to get a high-quality PDF.

The release also brings engraving improvements like nested tuplets and octave clefs.

Asking your manager for conference budget can be harder than giving a talk. So we wrote the letter for you.

Our #JCON2027 convince-your-boss letter starts with "Dear {{JavaLovingAndTotallyAwesomeBoss3000}}" and gets serious from there: the talks, the Mentorship Hub, 1:1 meetings with speakers, a certificate of attendance.

You fill in your name, your project and the prices. Right now, blind tickets are 30% off.

New on Foojay: Lottie4J 1.2.7 focuses fully on performance, with no new features. @frankdelporte explains how images are now decoded once and track mattes reuse canvases and buffers. In the profiling run, GC pauses dropped from 531 to 177.

Note: use 1.2.8 instead, as it fixes a regression with track mattes of different sizes.

I have been venting a lot about #JDBC driver in that context, and I want to say something positive: The Clickhouse one is so well documented:

https://clickhouse.com/docs/integrations/language-clients/java/jdbc

especially wrt type mapping (super helpful), and than I haven't even covered the fantastic page on date / date time (some people will relate to that very hard):
