[Message part 3 (text/plain, inline)]

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.

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.

Leo
