IllegalArgumentException on Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null)

[Hendrik Schreiber]

Hi,

on calling Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null) I 
get the following exception:

java.lang.IllegalArgumentException: Comparison method violates its general 
contract!

        at sun.awt.datatransfer.SunClipboard.getContents(SunClipboard.java:144)

I was not able to reproduce this, but as this happened on startup, I guess it 
has to do with whatever was already in the system clipboard..
Perhaps somebody wants to take a look at this.

Cheers,
