Subject Re: [classlib][sql] A RI's bug of SerialBlob.getBytes(long position, int length)?
Date Thu, 14 Dec 2006 09:30:01 GMT
That one? If you are talking about the problem mentioned in your
initial message

then +1 from me for following the spec since I don't understand RI's
behavior at all. Please note that even the exception message itself
contains typos :)
