Result:

<ServiceExceptionReport version="1.1.1"><ServiceException code="InvalidFormat">
Can't parse XML request.
  </ServiceException></ServiceExceptionReport>

There's a double "??" causing the error. It seems to be the error causing WMSEndpointTileSourceTest.testDefaultLayerSetInMaps to fail too. Seems to be a regression from r13878.
