This is the ugly code trying to get the content length for a resource. I think this code is unchanged, it's now just invoked different and maybe the reporting of the exception is new. However, the exception is swalled, so your provider should still work.
But maybe we have to revisit the code in order to properly avoid the exception if possible.
