Java applications no longer socksify correctly

The details
Newer Java versions, i.e., Java 1.8, prefer IPv4 over IPv6 as opposed to native IPv4. And that doesn’t work correctly with the OpenText socks client. There’s a command line option to change this behavior of the JRE

The solution
This is the way to disable Java’s preferences for using IPv6 on your PC. Run the following from a Command prompt.

C:\> setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true

It doesn’t break IPv6 funciotnality. All it does is stop Java from trying to use IPv6 for IPv4 connections.

Once we applied this fix a few of our Java applications that failed with the newer JRE began to socksify properly once again using the Opentext socks client.
