Fix some minor bugs (#745)

* Include other member variables in copy constructor

* Add break to switch cases

* Implement equals() in classes extending Comparable

If equals() is not overridden, the equals() implementation is not consistent
with the compareTo() implementation. If an object of such a class is added
to a collection such as java.util.SortedSet, this collection will violate
the contract of java.util.Set, which is defined in terms of equals().
