In essence, that means that I can no longer control whether and how a caller makes an instance of my class, and it also means that I can create instances of classes without providing the bare minimum of information they need for initialization.
Consider the following example:
First of all, you're not supposed to instantiate an Integer directly. You're supposed to use a literal or one of the valueOf() factory methods. Secondly, if you DID instantiate an Integer directly, then what would it even mean to instantiate one without a value?
Remember, according to your proposal, Integer should inherit the parameterless constructor from the Number class.

There are conversion rules that can map DOS paths to this notation and they necessarily include the drive ID. So "C:\Program Files\java" maps as "/C:/Program Files/java". Resolving in the other direction is ambgious, so expect that "/" will map to the root directory of the currently-logged drive.
Assuming you're not doing something stupid like uploading/creating/altering files within the WAR directory structure. Which will fail horribly on an unexploded WAR.
One final note. Java is a very bad language to use a "current directory" in. There's only one current directory for a given JVM instance, and since many processes may be running under that JVM, you can not be 100% sure that one of them might change the current directory programmatically at any given time. So as a rule, absolute paths are preferable, the Universal path notation is likewise preferable and ideally that path should include the currently-logged disk when running Windows.

If this spliterator can be partitioned, returns a Spliterator covering elements, that will, upon return from this method, not be covered by this Spliterator.
If this Spliterator is ORDERED, the returned Spliterator must cover a strict prefix of the elements.
Unless this Spliterator covers an infinite number of elements, repeated calls to trySplit() must eventually return null.
