I suppose you could restore the call, but since we are in a disposer thread throwing an exception doesn't seem like the right thing to do. You could log the error, but if we are sure there can be no pending errors, it might not be worth the effort.

Yes Kevin, After looking at the code it can be concluded that there are no mismatches. So It seems good to remove those checks. But just in case of safety can keep those as logs too.
