Simone Tripodi commented on CHAIN-101:
--------------------------------------
-1
* implementing via delegation forces implementing all {{Map}} methods;
* where _higher flexibility_ is? just to back different {{Map}} implementation
that could be potentially not thread safe?
> Change ContextMap from an inheritance based to a delegation based design

> Currently ContextMap extends ConcurrentHashMap, but there is nothing we gain
> from this design decision. A delegation based implementation that takes a Map
> as constructor arguments and delegates calls to the wrapped map yields higher
> flexibility.
