I have an wildfly with 10 EARs inside /standalone/deployments.

Each of these EARs has a lib called “my-lib.jar” on the /lib directory.

This Lib has a class called MyClassUsedForSomethingImportant.java which has a static variable. The purpose of this static variable is to store an unique ID generated progamatically for each EAR. Its unique per EAR!!!!

My question is: This static variable is shared between ALL EARs or it is contained on the scope of each EAR?

The problem that could occur: If static variables are shared between ALL EARs, then the static variable will be overwritten every time an EAR sets a value to it, and this is a problem.

The goal: Every EAR should have a variable that is not shared between all EARs.
