Subject: [bug#46451] [PATCH 0/2] OpenJDK: Fix NullPointerException when accessing fonts
Date: Fri, 12 Feb 2021 00:14:05 +0100

[Message part 1 (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.
