> Calling String.replace(CharSequence, CharSequence) with the empty String as the first argument throws an OutOfMemoryError as it goes into an infinite loop trying to substitute the sequence at the same point until the StringBuilder fills the heap.  The RI in this case substitutes the replacement String at the start, inbetween each character and at the end.
