Eclipse Vert.x

#1258 and #1264 provided a way to find out if there was a CSRF validation error by comparing failure error message to CSRFHandler's ERROR_MESSAGE constant.

This is broken in Vert.x 4.1.1 because CSRFHandlerImpl now fails with common Java exceptions like IllegalArgumentException with hard-coded strings:

ctx.fail(403, new IllegalArgumentException("CSRF validity expired"));

Need to verify and update the tsdocs links to include all the new generated modules.
