Hi Naoto,
Yes, I did look through that code and bug 5046319. Unfortunately, it happened
when JAXP was standalone, the history of the change was lost.
The variable "buf" seems to be an instance variable that serves to cache the
text read. That part had been changed as well. Furthermore, if buf starts with
zero length, the call to getTextCharacters would still result in
IndexOutOfBoundsException.
Maybe the commented code can be removed, I kept them as is in case they may be
useful reference as a history.
