isLast() and empty ResultSet

Hello,

I implemented an Iterator interface iterating over a ResultSet. Therefore
I rely on isLast() to implement the Iterator#hasNext() method. This works
fine unless the whole ResultSet is empty.
For empty RresultSets, isLast always returns true.
Stepping through the code I found the reason therefore. Line 544 of
AbstractJdbc2ResultSet says
if (rows_size == 0)
return false; // No rows.
At least to me this is suspicious as I would return the opposite. Might that
be a bug or is there any other reason to behave like this?

I am using JDBC Driver 8.0 Build 311 and Server Version 8.0.2.

Regards
Rüdiger
