Indeed, that it does.  At least for 9 and 11, which I've invoked
directly from their store paths.

I've pushed your patches with small changes to the commit messages and
followed up with an indentation fix.

These two patches fix a NullPointerException in the OpenJDK packages.

The patches apply only to OpenJDK9 and OpenJDK11, but with inheritence
all OpenJDKx with x\in[9..14] are covered.

Here is the bug report:

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=41177

In order to test it you can use the following Main.java:

~~~~~~
import java.awt.*;

public class Main {

    public static void main(String[] args)
    {
        String fonts[] =
            GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();

        for ( int i = 0; i < fonts.length; i++ )
	    {
		System.out.println(fonts[i]);
	    }
    }
}

~~~~~~~~
Compile: javac Main.java
Run: java -cp . Main

It should print a list of the available fonts.
