Closing this as a duplicate of JDK-8165867 which has a fix with 8u112 b16 and 8u122 b02 b16 and submitter confirmation that the issue is not reproducible after updating OS to 10.12.1
07-12-2016
Checked this on MAC OS X Sierra (10.12.1) with 8u101 b13 and could reproduce the issue partially. The test url, https://www.rbvi.ucsf.edu/home/tef/ssh/ fails to load completely or remain suspended. The issue seems resolved with 8u112 b16. Awaiting confirmation from the submitter with 8u122 ea.
