I had tried a ton of suggested fixes for the issue before stumbling upon this work around. In it, I link to the Apple discussion forums at the bottom, where people have been saying that this workaround fixes the issue for them.

updating java for mac-19

Recently, I was trying to get a Java applet to run in the same way on 2 i Macs and my Mac Book Air.

The applet is a simple vpn client from Juniper that lets me access a Citrix Desktop from any Mac that I can install the Citrix receiver client on so I can work on 'Company stuff' from a large screen i Mac when I'm sat at home or from my Mac Book when I'm on the road (it works fine over 3/4G).

Simply put, you can have multiple versions of Java in different places.

What was happening on the not-working Macs was that the jdk versions were being used, and the Juniper vpn client won't work with them.

I use the same mechanism to launch 'site specific browsers apps' created by Fluid.

For example I have a JIRA app wrapper which looks for anything staring with

For Safari, enable the Develop Window and use an option in there that works. [crarko adds: I don't have an older system active at the moment to try this.

It's inevitable that older software becomes obsolete, the same way older hardware does.

To fix things for the moment I simply removed the jdk folders.
