I'm given the following instructions:

You must set the sun.lang.ClassLoader.allowArraySyntax system property to true by adding the following to the JVM arguments:


How do I do that? I go here:

enter image description here

But I cannot edit the Runtime Parameters in the System tab. And even on the Users tab, it will not save my changes. I need this to be a system-wide change.

I ran the Java Control Panel by Right-clicking it and choosing Run as Administrator. I'm full admin on this machine.


Double-click the 'Runtime Parameters' box in the USER side and edit it there.

These changes will get propagated to the SYSTEM side.

Please don't ask me why, I don't want to consider the ramifications.
