Ok. You have AWT embeded into SWT right? So you have got two different
threads running (one for AWT and one from SWT) if you want to to do
something from the AWT-Thread in SWT you need to use asyncExec/syncExec
calls.

Display.getCurrent().syncExec( new Runnable() {
    public void run() {
        Display.getCurrent().addFilter(....);
    }
});
