Discovering available printer services leads to a runtime crash

[gradinac]

The following simple program attempts to find the default printer service: Printer.java:

import javax.print.PrintService;
import javax.print.PrintServiceLookup;

public class Printer {
    public static void main(String[] args) {
        PrintService pserv = PrintServiceLookup.lookupDefaultPrintService();

        if (pserv != null) {
            System.out.println("We have a print service: " + pserv.getName());
        } else {
            System.out.println("No print service available!");
        }
    }
}

Compiling and running it on the JVM on a machine without a printing service leads to:

$ javac Printer.java
$ java Printer
No print service available!

However, building and running the same program as a native-image leads to:

$ native-image Printer
[printer:39908]    classlist:     865.33 ms,  0.96 GB
...
[printer:39908]      [total]:  33,418.31 ms,  3.99 GB
$ ./printer

This crash shouldn't happen on native - I suspect the most likely reason for it is not adding the AWT libraries that contain this method to the image.

This issue is reproducible on Java 11, Linux-AMD64 - on master.

I don't think java.desktop is supported. AWT/Swing is not, so you can safely assume that any dependency from java.desktop will not work. (this is not because Graal has issues, this is because awt/swing is written this way)

how to solve it?
