Bug#907990: libswt-gtk-3-java: no swt-gnome-gtk in java.library.path

[Jochen Sprickerhof]

Package: libswt-gtk-3-java
Version: 3.8.2-5
Severity: normal
Control: affects -1 + jameica

Hi,

I actually found this in jameica but it requires a lot of state to
trigger this, so I extracted this minimal example:

--%<--
public class Main {
  public static void main(String[] args) {
    new org.eclipse.swt.widgets.Display();
    org.eclipse.swt.program.Program.launch("");
  }
}
--%<--

$ javac -cp /usr/share/java/swt.jar Main.java
$ java -cp /usr/share/java/swt.jar:. Main

Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
        no swt-gnome-gtk-3836 in java.library.path: [/home/jspricke/.local/lib, ., /usr/java/packages/lib, /usr/lib/x86_64-linux-gnu/jni, /lib/x86_64-linux-gnu, /usr/lib/x86_64-linux-gnu, /usr/lib/jni, /lib, /usr/lib]
