That is weird.

I will try to find time to put together a selfcontained testcase later
on (you could speed this up by sending me one :)

Sorry -- not thinking there :)

What I'd expect to see is this sequence:

execute() returns false (no resultset for this result)
getUpdateCount() returns 1 (1 row inserted)
getMoreResults() returns false (no resultset for this result)
getUpdateCount() returns 1 (1 row inserted)
getMoreResults() returns true (resultset present)
getResultSet() returns an appropriate resultset for the SELECT
getMoreResults() returns false (no resultset for this result)
getUpdateCount() returns -1 (no more results)

Your code seems to be expecting something different..
