when i'm using clipboard.setContents to reset clipboard information it
is breaking clipboard.getContents. (getContents will return whatever
setContents set regardless of the outside program putting information
on the clipboard. this was not a problem until setContents was added.
am i doing or expecting something wrong?

java.awt.datatransfer.StringSelection ss = new
java.awt.datatransfer.StringSelection(s);
       this.clipboard.setContents(ss, ss);

(...)

this.clipboardTransferable = this.clipboard.getContents(null);
       try {
           return
this.clipboardTransferable.getTransferData(java.awt.datatransfer.DataFlavor.stringFlavor).toString();
       }
