I have a web application in which the dependencies pull in two jars called:

1. javassist-3.9.0.GA.jar
2. javassist-3.20.0-GA.jar

when I package the WAR I have both of these in the WEB-INF/lib directory, my question is that the application is running and why I wouldn't get any issues because apparently I have same classes in both jars and there should be issues right?
