Summary

Bindings need to be creatad newly via jextract

Motivation

Java 22 will be released by the end of the month.
These bindings have already been successfully generated with Java 22 for the minimal variant.

Nevertheless, using jextract fails for the other two variants due to a bug in jextract.

The generated bindings contain a lot of dumped in locations like the following, that make it impossible to compile the code:

Considered Alternatives

No response

Anything else?

The bindings for minimal were generated on Java 22 with jextract 22
JDK version 22-ea+28-2271
clang version 18.1.0rc (http://git.linaro.org/toolchain/jenkins-scripts.git 09f505cadfbe9987730e641398ab9a2ca0cdb67f).

[purejava]

The bindings for libappindicator-gtk3-java-full and libayatana-appindicator-java-full can be generated with jextract, when the tool was compiled with clang+llvm-13.0.1 before.
Nevertheless, this requires an additional package installed for building: yay -S ncurses5-compat-libs.

Done with cfa3c3c and 7b89573.
