Shouldn't HashSet/Map use Arrays.hashCode(x[]) ?

[Ulf Zibis]

Otherwise e.g. int[] as key for HashSet/Map doesn't make any sense.

I use a class where the content of an int[] defines the uniqueness or 
there instances.
Before I create a new instance, I have to check if there is just one for 
the same int[] content.
Using the current HashSet/Map implementation does not serve this need.
It seems, that I should first instantiate a temporary object containing 
the int[], hash it in the set/map, and later throw it away. :-(

Maybe another reason for solving
