> Java 8 redefines the method keySet() on ConcurrentHashMap to return a narrower type than
the standard return type given in the Map interface.  If the code is compiled in Java 8 and
then run under Java 7 this causes linking issues.
> Avoid these issues by always declaring variables in terms of the interface ConcurrentMap
