ClassCastException in MessageCracker

QuickFIX didn't respond correctly to a ResendRequest from our counterparty.

Normally this is what happens when I have to restart during the day:

XXX = Me
YYY = Counterparty

ResendRequest from YYY:

Correct respons from QuickFIX/J:
8=FIX.4.29=9435=434=715043=Y49=XXX52=20060718-08:07:32.18456=YYY122=20060718-08:07:3236=7204123=Y10=080

Yesterday's scenario:

8=FIX.4.29=6735=A34=3049949=XXX52=20060718-11:29:33.50456=YYY98=0108=18010=004

ResendRequest from YYY:

The correct Sequence Reset message is missing from QuickFIX/J...

8=FIX.4.29=7635=134=3050249=XXX52=20060718-11:29:42.75756=YYY112=Test
