java.util.ConcurrentModificationException: null

com.cimba.gsr.fragments.SessionsFragment$4(SessionsFragment.java:201)
Sometime in log output after a class name there is a Dollor symbol ($) in the message what does that mean? I thought it's the method name or the variable name in the class that caused the exception but in this case it doesn't make sense (SessionsFragment$4 it can't be the name of a method or variable). so what is it ?
