I thought you were having a problem executing java programs. Why do you need a global setting if you are using a commandline with the needed option?

What you posted was paths to folders.
What I am talking about is the commandline used to execute a java program. This is an example of a commandline:
java -Djava.net.preferIPv4Stack=true -jar...

Where does the commandline with the java command etc come from?
Can you modify that commandline to include that option?

For example on Windows7 and XP I can change the registry entry.

You'll have to wait until someone with Windows 8 comes along.

I can't believe the stack trace in the error message would be the same.

Does the code work if you put it in a small program and execute it from the commandline?
