Bug 1007803

Description of problem:

In gcj, calling java.awt.Toolkit.getDefaultToolkit() with the DISPLAY environment variable not set leads to abrupt termination of the process with exit code 1.


Version-Release number of selected component (if applicable):

At least reproducible with java-1.5.0-gcj-devel-1.5.0.0-43.fc19.x86_64 but also already with java-1.5.0-gcj-devel-1.5.0.0-29.1.el6.ppc64.


How reproducible:

Always.


Steps to Reproduce:

> $ cat Test.java
> public class Test {
>     public static void main(String[] arguments) {
>         try {
>             java.awt.Toolkit.getDefaultToolkit();
>             System.out.println("good");
>             System.exit(0);
>         } catch (Throwable e) {
>             e.printStackTrace();
>         }
>     }
> }
> $ /usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/bin/javac Test.java
> $ echo $DISPLAY
> :0
> $ /usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/bin/java Test
> good
> $ unset DISPLAY
> $ /usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/bin/java Test
> 
> (.:31017): Gtk-WARNING **: cannot open display: 
> $ echo $?
> 1
