> ExpressionMessageFilter will pass some message with tag's hash code less than
> 0.
> This is not correct. After sql filter feature added, the tag's hash code in
> consume queue may be replaced by the address of consume queue ext. And,
> differences between them are:
> 1. Tag's hash code is an integer, values is between Integer.MIN and
> Integer.MAX.
> 2. Address of consume queue ext is a long, values is between Long.MIN and
> Integer.MIN - 1.
> So, actually, they are not conflict.
