MSIE does indeed not support the content type of application/xhtml+xml. The page should be served with a content type of text/html (you can verify that with HTTP/web developer tools).

One of the ways is defining it using the contentType attribute of the tag. Another way is calling HttpServletResponse#setContentType() in some web filter. Or, completely different, perhaps it's been done afterwards by the webserver itself or by some proxy in the line.
