[ BUILD # : 201003140200 ]
[ JDK VERSION : 1.6.* ]

Using the remove(int) method of a Vector and/or ArrayList is marked with this
hint if the Vector and/or ArrayList  type specified is non-integer.

For Example:

ArrayList <String> test = new ArrayList<String>();
test.add("Test");
>test.remove(0);

It acts as you are making a call to remove(Object);

Probably not a biggie but it can feel you editor of false hints if you use that
a lot.
