MacOS – How to launch web start on 10.10 OSX

I have the same issue. When I use a proxy.pac file certain applications fail to pick up the settings. Among these are:

• Firefox
• Chrome
• Java apps (like eclipse)

Some apps that do work with the pac file are:

• Safari
• Skype
• Adium
• Evernote

What I have found though, is that when I manually add a proxy server to the system preferences it is picked up by all applications. So something in the pac handling is broken. Maybe old/new APIs in Lion?

The oracle java version here (1.7.0_09-b05) is old and is blocked by Safari as a security risk a see this Apple note. Upgrade to the current JDK which is currently Java SE 7u21.
