resultset.last() return wrong value if resultset has only one result

Using resultset.last(), when resultset has one row, last() position correctly cursor set on last row, but return the "false" value. In this case, "true" value is expected.

JDBC javadoc

true if the cursor is on a valid row; false if there are no rows in the result set

Other positionning/verification methods (like isBeforeFirst(), isAfterLast(), isFirst(), isLast(), first(), absolute(row), relative(row), previous(), next()) return correct result.
