>             Fix For: 4.1-beta1
> At the moment AbstractSessionInputBuffer#read(byte[], int, int) always copies input to
the internal data buffer prior to copying it to the destination buffer. The performance of
this method may potentially be improved by eliminating intermediate data copy operation and
reading input directly to the destination buffer, especially when dealing with large chunks.
