1.13.2022102814 is a really old prerelease build. We focus on working on the latest version only and don't backport bug fixes. Are you able to upgrade to a newer version? It might be fixed there.

I am having this issue moving to Antigravity from standard VS Code.
In standard VS Code there are extensions by Microsoft;
Debugger for java
Extension pack for java
Container tools
Kubernetes
Gradle for java
Maven for java
....
and these are not available in Antigravity. Maybe providing Antigravity users alternate extension list if the Microsoft ones are not available would be nice.
In Antigravity there is
Java Platform Extension for Visual Studio Code
by Oracle but without debug support.
and a there a
Debugger for Java
by vscjava
which required the extension [Language Support for Java(TM) by Red Hat]
this solved issue "Antigravity: can not start Java app via Run and Debug" which loads launch.json.
There are other related issues to this like
Configured debug type 'java' is not supported. #290

The Java extension pack is published on OpenVSX and should be available on forks of VS Code, such as Antigravity and Cursor: https://open-vsx.org/extension/vscjava/vscode-java-pack.
In fact, I tried installing Antigravity, and it's listed under the recommended extensions for me.
