Just to add my final solution for adding a MacOSX Dock icon in a pure-java application:

public boolean exists(String className)
{
    try {
        Class.forName( className, false, null );
        return true;
    }
    catch (ClassNotFoundException exception) {
        return false;
    }
}

public void setIcon( BufferedImage icn )
{
    if ( exists( "com.apple.eawt.Application" ) )
    {
        com.apple.eawt.Application.getApplication().setDockIconImage( icn );
    }
}

This silently ensures the class is available and the executes the setDockIconImage() method. Works very well for me and it does not interfere with other platforms.
