Anyone know about attacks on static variable in JVM? Any links?

Im subbing because i have no idea what youre talking about

Doing something at work and I used static variables. They need to be pretty secure. I talked to a coworker about them and he said that there are ways to attack static variable. I'm unsure of the way but we can look into the JVM memory and find where this class definition is held and then access the static variable and change it or delete its value( I guess via reflection or by iterating over all memory objects) . That's what I need to know. Any clues anyone?

Oh, that. It was patched out in java7 (8? Not sure.)
