>      Project: XalanJ2
>         Type: Bug
>   Components: Serialization
>     Versions: 2.6
>  Environment: Operating System: All
> Platform: All
>     Reporter: J Desrochers

>      Fix For: 2.7
>  Attachments: WriterToUTF8Buffered.patch
>
> The rework to chunk buffers of data in the write(char [], int, int)
> method can lead to an integer overflow in the computation of the end_chunk
> then start_chunk variables. When the latter value becomes negative it
> leads to an illegal array reference into the chars array. With the numbers
> in play a data block of 4MB can lead to this situation.
