------------------------------------
Hi Florin,
I understand that this bug needs fixing. However I don't believe that
LateralTCPListener is the right place for the fix. This needs to be addressed
in IElementSerializer.deSerializeFrom() because this method is used in several
places.
Please note that I will not fix this issue in the jcs3 release anymore but in
jcs4.
