Seriously, I just wasted an hour trying to get Hetzner's KVM java web app to run on my Mac, because after having a couple of tickets closed and finally calling support directly, I was told firmly that the applet was from a third party vendor over whom they had no control, there was no other alternative, and they had no plans to support a better way to access the KVM.
I had to use Safari instead of Chrome, then CAREFULLY upgrade Java making sure Oracle didn't trick me into installing any toolbars, then find the Java control panel in the system preferences, which was just too awesome to be constrained by the limited confines of the Mac system preferences windows, so I had to read about how "The Java Control Panel opens in a separate window" because obviously it is so much more important than all other control panels, so I then pressed the "Reopen the Java Control Panel" button, which did what it promised after a half second pause, then I had to click around to the Security tab to find the Exception Site List, press the "Edit Site List..." button to bring up the "Exception Site List" dialog in all its glory and splendor, then press the "Add" button, then type an https url with a numeric ip address and port number into the field, then click a long series of "OK" buttons window close icons, then go back to the web browser, refresh the page, click through another series of threatening warning dialogs, to finally get a bottom of the barrel KVM applet.
And it was convinced I was using a German keyboard, so I couldn't find the punctuation characters I needed to type shell commands, and the Z and Y keys were switched. I had to press and shift-press every key to make a little table of substitutions, and then punch each character in carefully instead of touch typing.
One new thing I found during my Java adventure: the system Java control panel has an "Advanced" tab, and if you scroll way down to the bottom, there is a checkbox labeled "Suppress sponsor offers when installing or updating Java". It was un-checked by default of course. I suspect it's not actually hooked up, it's just a placebo, and exists to make me lower my guard next time I install a Java update. I'm not falling for it.
