There is no size() method on ResultSet. And no way to know the number of elements
thrown away with limit/offset.

Hello again,

I don't think so. JBoss calls the database without any LIMIT/OFFSET-clauses and gets
back a collection/resultset of primary-keys. It should only do a size() or som
I think there is no alternative but using count(*).
If Jboss needs to count the number of records in the DB, then the resultset will need
to be traversed, causing an even bigger bottleneck.
