Java-GI 0.14.0 has been released!

Release notes: https://github.com/jwharm/java-gi/releases/tag/0.14.0

Highlights:
- all bindings updated to #GNOME 49 version
- #JSpecify nullability annotations everywhere

For those who don't know, Java-GI is a #Java language binding for GNOME (and other GObject-Introspection libraries) based on the new FFM API in OpenJDK. It's modern, fast, and very easy to use. Visit https://java-gi.org for more information!

70 % aller Fehler in Java-Produktionscode sind #NullPointerExceptions. Mit #NullAway & #JSpecify lassen sie sich statisch verhindern – ohne große Umbauten. Richard Gross zeigt, wie Teams sicher & schrittweise migrieren.

@SpringCentral @UberEng

I'm looking for success stories using the null checker in #vscode #java, which I think is based on #eclipse. I would like to use it but I'm swimming in false positives from Java standard library. I should not have to specify that Optional.of() and ofNullable() return NonNull.

Note: using #jspecify

I'm adding JSpecify nullability annotations to Java-GI, and learning a lot along the way. For example, a nullable array with non-null Strings is a `@NonNull String @Nullable [] array`.

Today I learned you can annotate the "..." vararg symbol too: `public void foo(int i, @NonNull String @Nullable ... strs)`
