RFC 4627public static boolean isNumericStop(int codePoint)
The slash character '/'
is not itself a valid terminator, but
if the next character is '/'
or '*'
then the number is
followed by a comment. Since this method cannot perform the look-ahead
necessary to make that determination, it returns false
for the
slash.
