Hi Peter,
I know it is matter of taste, but don't you think this:
269 for (char c = current();
270 c != ';' && c != '.' && c != '/' && c != '[' &&
271 c != ':' && c != '>' && c != '<' &&
272 !Character.isWhitespace(c);
273 c = current())
274 {
is easier to read than the long or-condition which is then negated?
Best regards,
Andrej Golovnin
