Hi All,
I am testing GeoServer in the following environment:
O.S: Windows 10 Home (Version 21H2)
Java: OpenJDK 17.0.2
GeoServer 2.22.1 (Platform Independent Binary)
The first error I noticed was on the Status server page. When clicking on the menu, it displays the screen:

The second mistake is when clicking on some layer in Layer Preview. It does not load the layer and the following error appears in the console:

When going back to Java 11 (JDK 11.0.2) everything works normally again.

So JDK 17 is experimental.
Did you apply the required changes as shown at
https://docs.geoserver.org/2.22.x/en/user/production/java.html#running-on-java-17-experimental
?

An error like:
Could not initialize class java.awt.GraphicsEnvironment$LocalGE
makes me think the server is headless, and nothing told Java that was the case. Try adding “-Djava.awt.headless=true” among the java command line parameters
and see if that helps
Cheers
