The ns
parameter may be negative, even though the skip
method of the
Reader
superclass throws an exception in this case. Negative values of ns
cause the
stream to skip backwards. Negative return values indicate a skip backwards. It is not possible to skip
backwards past the beginning of the string.
If the entire string has been read or skipped, then this method has no effect and always returns 0.

readAheadLimit
- Limit on the number of characters that may be read while still preserving the mark.
Because the stream's input comes from a string, there is no actual limit, so this argument must
not be negative, but is otherwise ignored.java.lang.IllegalArgumentException
