Looking at the code again more closely, this might be a mis-diagnosis. 
The actual code there before line 117 where the WARN is logged is:

        try {
            final InputStream stream = super.getInputStream();
            return saveAndClone(stream);
        } catch (IOException ex) {
            log.warn("{} HTTP resource was inaccessible for
getInputStream(), trying backing file.",
                    getDescription()); 


So either:
1) the super.getInputStream() is throwing b/c of issues with the
HttpClient call (what I assumed before)

OR

2) (what I didn't see before)  the saveAndClone(..) call to create the
backup file from the HTTP response is throwing.  The log output is
misleading by itself, because it then tries *again* to load from the
backing file.  I didn't get that before.

I want to see the DEBUG output, but I'm suspecting #2.
