Compile-on-Save drops static initializer (vanilla javac)

Very great to see Compile-on-Save now working without the external nb-javac plugin! Here's the first bug I've found around this. To reproduce, create an empty maven-based Java project and add the following class:

public class StaticInitializerExample {
  private static final String SOME_CONSTANT;
  static {
    SOME_CONSTANT = "I am a constant.";
  }

  public static final void main(String args[]) {
    System.out.println(SOME_CONSTANT);
  }
}

Do a clean build and run. The application will print, "I am a constant."

Now do any trivial change to the code, such as adding a comment, and save. Run again. The application will now print "null", rather than the correct output.

Tested on both Java 11.0.11 and Java 17-ea+25. I also tested with NetBeans 11.3 with nb-javac installed; in that case the output is correct (still "I am a constant."). In the latter case you can also change the constant in the static initializer, and CoS will apply the change correctly.
