Fix issues found by FindBugs: EQ_DOESNT_OVERRIDE_EQUALS

http://findbugs.sourceforge.net/bugDescriptions.html#EQ_DOESNT_OVERRIDE_EQUALS

Added @Override implementations of equals() and hashCode() in the derived classes.

TODO: The implementations in the derived classes redirect to the implementations
in the base class. This needs to be revised and fixed/updated as appropriate.
