You'll get a copy of static variables per Class instance. That's at least one per JVM, and more if the same class is loaded by multiple ClassLoaders. In short, they are not shared across servers in a cluster. If you have a need for such sharing, google for "java distributed cache" and see other people working on the problem.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
