* Tests fix for BUG#74998 - readRemainingMultiPackets not computed correctly for rows larger than 16 MB.

* This bug is observed only when a multipacket uses packets 127 and 128. It happens due to the transition from positive to negative values in a signed byte
* numeric value (127 + 1 == -128).
*
* The test case forces a multipacket to use packets 127, 128 and 129, where packet 129 is 0-length, this being another boundary case.
* Query (*1) generates the following MySQL protocol packets from the server:
* - Packets 1 to 4 contain protocol control data and results metadata info. (*2)
* - Packets 5 to 126 contain each row "X". (*3)
* - Packets 127 to 129 contain row "Y..." as a multipacket (size("Y...") = 32*1024*1024-15 requires 3 packets). (*4)
* - Packet 130 contains row "Z". (*5)

* @throws Exception
