    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same
    Java package; see
    https://groups.google.com/g/google-web-toolkit-contributors/c/CqYH59Dt_rQ/m/uVGW1QdUsXUJ
    for details.

    The summary is that it ignores one file in favor of the other.

growing, and very soon had to kneel down on the floor:  in
another minute there was not even room for this, and she tried
the effect of lying down with one elbow against the door, and the
other arm curled round her head.  Still she went on growing, and,
as a last resource, she put one arm out of the window, and one
foot up the chimney, and said to herself `Now I can do no more,
whatever happens.  What WILL become of me?'
