Hi Mike, I'm sorry but I've no time to investigate if the problem is on the cmislib side or on the alfresco side. Nevertheless, I recently completely reworked the cmislib library to make it py2 py3 compatible and at the same time I replaced the dependency on httplib2 by requests. ( https://github.com/apache/chemistry-cmislib/pull/12) It could be interesting to make a try with this new version of the library and see if the problem is also present into this new one. If the problem comes from cmislib, personally I would prefer to correct it in this new version and speed up thus its release.
