Simply put, you can have multiple versions of Java in different places.
I think the actual hint here is a reminder that if a site misbehaves, changing the user agent can be an effective troubleshooting tool.] Usually I want to open Gmail in Chrome and URLs pointing to my development server in Firefox. There is this nifty free app called Lin Castor that enables you to register your own handler for an URL.
Although it had beed designed to register your own non-standard URL schemes, it can intercept standard http and https as well.
On two of the Macs, as soon as I fired up the Citrix app, the Java vpn window would show 'error'. Then I remembered that I had done some Java development in the past and installed various jdks from Oracle so I ran: That was on the working Mac.
Then I remembered the difference between 'System' Java, Java plugins, and Java development kits.
In Lin Castor (which you need to double-click twice to fully open for editing): on handle_url(args) if (|URL| of args starts with "https://mail.google.") then tell application "Google Chrome" open location |URL| of args end tell else if (|URL| of args starts with " then tell application "Firefox" open location |URL| of args end tell else tell application "Safari" open location |URL| of args end tell end return 1 end Obviously you should customize the code to suite your own specific needs.
You can validate the script right in Lin Castor before saving/activating it.
I'd be curious to know from Mac OSXHints users whether they are experiencing this problem in the first place and if the workaround works for you, too.
I'd also like to understand why this works and why the problem even exists.
Web applets still use the up to date, secure version 1.7 plugin.
