OpenJDK 17 --enable-preview breaks error reporting

I wanted to use the new switch syntax that's still a preview in 17. I changed my maven pom.xml to have

<plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> <configuration> <compilerArgs>--enable-preview</compilerArgs> </configuration> </plugin>
In the Syntax Server output window it has,

[Error - 1:49:59 PM] Connection to server got closed. Server will not be restarted.

It stops highlighting compiler errors/warnings in the editor. Removing the --enable-preview stuff from pom.xml solves the problem, but then I lose the error reporting.

It breaks regardless of whether or not my code uses any preview features.

Environment

• Operating System: Ubuntu 20.04
• JDK version: openjdk version "17.0.3" 2022-04-19
• Visual Studio Code version: 1.69.2

Additional Informations

Start with the pom.xml compilerArgs setting and the Syntax Server output while reproducing on Ubuntu 20.04 with OpenJDK 17 and --enable-preview. Investigate the server connection closure and compare error reporting with and without the setting; done means compiler errors and warnings remain available when preview is enabled.
