Hi list,

I apologize, but on further evaluation, I have determined that it
definitely works in 3.4.0 but not in 3.5.0.  So, the scope of changes
(since 2017 July) is a bit broader.
Also, for reference, here is a link to the client method
<https://github.com/pan-dora/ldp-client/blob/master/src/main/java/cool/pandora/ldpclient/LdpClientImpl.java#L875-L879>.
If you need detailed server logs, please let me know.
