We have an automatic proxy config which uses the myIpAddress for example below:

   var workstation_ip = myIpAddress;
    if (isInNet(workstation_ip, " 10.64.128.0 " , " 255.255.128.0 " ) ||
    isInNet(workstation_ip, " 10.65.160.0 " , " 255.255.224.0 " ) ||
isInNet(workstation_ip, " 10.65.192.0 " , " 255.255.192.0 " ) ||
    isInNet(workstation_ip, " 10.66.224.0 " , " 255.255.224.0 " ) ||
    isInNet(workstation_ip, " 10.67.32.0 " , " 255.255.224.0 " ) ||
    isInNet(workstation_ip, " 10.67.100.0 " , " 255.255.252.0 " ) ||
    isInNet(workstation_ip, " 10.67.104.0 " , " 255.255.248.0 " ) ||
    isInNet(workstation_ip, " 10.67.112.0 " , " 255.255.240.0 " ) ||
    isInNet(workstation_ip, " 10.67.144.0 " , " 255.255.240.0 " ) ||
    isInNet(workstation_ip, " 10.67.160.0 " , " 255.255.248.0 " ) ||

This determines the local IP address and provides a specific proxy depending on your location.

I've tested and the .pac file works absolutely fine for 1.5.06. However there must be new changes that the latest Java release stops the .pac file from working.

JUSTIFICATION :
Works for 1.5.06 the pac file.
Newer versions such as 1.6.27 and 1.7.25 fail.

Javatester.org says Object doesn't support this property or method when attempting to test the version.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Java applet launches and the version is shown.
ACTUAL -
Object doesn't support this property or method - error message popping up for newer Java versions 1.6.27 and 1.7.25 onwards.
