When I originally read your install instructions, it stated that HyperCon works with 1.7+ Java.
When I tried to use the SSH tab features with 32bit Java version 1.7.0_80, I would receive an error regarding "algorithm negotiation failure".
When I used HyperCon with 32bit Java 1.8.0_92 I had no errors using the SSH tab functionality.
This is when trying to connect to the OpenElec sshd
Let me know if you have any questions.
