It seems to be fixed in 3.17. The snippet below fails with 3.16 but works
fine with  3.17 and  trunk

public static void main( String[] args ) throws Exception
{
    Thread thread = Thread.currentThread();
    ClassLoader cl = thread.getContextClassLoader();

    Thread th = new Thread(() -> {
        try {
            XMLSlideShow ppt = new XMLSlideShow(new FileInputStream(args[0]));
            for (XSLFSlide slide : ppt.getSlides()) {
                List<XSLFShape> shapes = slide.getShapes();
            }
        } catch (Exception e){
            e.printStackTrace(); // prints
"java.lang.IllegalStateException: Schemas (*.xsb) for CTTable can't be
loaded " with poi-3.16
        }
    });
    th.setContextClassLoader(cl.getParent());
    th.start();
    th.join();

}

Tim, you should be good to release with poi-3.17, the fix is already there.
