This is mostly just a heads up for others - I don't expect to see this fixed in 10.11, but it wold be nice if it magically started working.
Juniper's SSL-VPN (Non-Pulse version) won't run under El Capitan - as soon as the Host Checker java applet is downloaded and executed, Java 8 barfs out.
This is the latest Java as well:
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
