Michael Smith 91e030ff08 Fixed the following Bag related problems:
- In Bag.java, the statement "If the bag contains less than i occurences,
the item item will be removed from the unique set" implies that if the bag
contains 5 occurences and i is 5, (5 is not less than 5) then the item will
not be removed from the unique set, even though there should be no more
occurances in the bag.

 - In AbstractBag.java, the documentation does not specify exactly what a
subcless needs to do to extend AbstractBag to make a concrete subclass.

 - AbstractBag.add(Object,int) has two calls to getCount(o), when only one
is necessary.  This wastes a few cycles to perform method invocations, a
map lookup, a cast, and a few comparisons.

 - The AbstractBag.equals(Object) method will incorrectly throw a
NullPointerException if a null value is passed.  The Object.equals(Object)
API specifies "For any non-null reference value x, x.equals(null) should
return false".

 - The AbstractBag.equals(Object) method will only work if the object
passed in extends AbstractMap or implements Map.  Neither of these facts
is documented, and neither is correct.  The contract for
Object.equals(Object) states: "for any reference values x and y,
x.equals(y) should return true if and only if y.equals(x) returns true. ".
Returning true when the argument is a Map is incorrect since he reverse
(the map checking to see if its equal to the bag) will most certainly be
false.  The same can be said for AbstractMap.  A subclass of AbstractMap
may add extra data to be stored within the Bag that must also be compared
for them to be equal.  The reverse comparison (specialized subclass equals
basic abstract bap) will fail.  You can read more about this in a three-
year old, but still valid java world article:
http://www.javaworld.com/javaworld/jw-01-1999/jw-01-object.html

 - if AbstractBag.remove(Object,int) is called passing in 0 as the number
to remove and specifying an object that exists in the bag, true will be
returned from the method. Per the Bag API specification, true should only
return when an object is actually removed.  Since no objects are removed,
false should be returned instead. Additionally, if a negative number is
specified, not only is the object not removed, but object(s) are *added*
(well, in the sense that it is equivalent of calling add(o, -i))

 - the uniqueSet() method returns the set of unique objects, however the
set is modifiable.  If the underlying map implementation has the set
backed by the map (as per the map contract -- so it should), then elements
can be removed from the unique set and have them removed from the
underlying map as well.  This causes consistency problems with the Bag
since _total will then be incorrect.

 - in extractList(), getCount(current) is called each time through the
inner loop, adding lots of extra overhead.  Reversing the loop (starting
at the count and going down to 0) eliminates the excess overhead.

Michael Smith 2af7a322ef Odd how that compiled for me before my commit, but it doesn't
afterwards (for obvious reasons)

Michael Smith ef5aa20db3 There is no backwards compatibility issue since this class is new
since collections 1.0.  Therefore, since the entire Map interface
is implemented, there's no reason to inherit from HashMap.

Michael Smith 95ccabfc7c Added a bunch of generic tests to the TestMap.java class. Also added
cooresponding changes to other tests.  These tests expose a few deviations from
the Map contract in BeanMap.  These should either be fixed, or BeanMap should be
documented to describe how it differs from the Map contract.
