Bug 1178: Fix cc10 regression caused by the fix for cc7.

Bug 1178 cc10: We no longer throw an ExceptionInInitializerError
    when X11 is not available.

Fix 1178 cc10: We need to use an X11 resource in the constructor
    in order to throw an ExceptionInInitializerError if X11 is not available.
    We can resolve this by query for the X11 display and screen inside the constructor.
