The other problem is that a small slice view of a large object keeps the large object alive, so a view user needs to think carefully about whether to make a copy or create a view, and later to copy views to delete the base object. This is not for beginners.

And this was important enough that Java 7 actually removed the long-standing feature of String.substring creating a string that shares the character array with the original.
