Recently I upgraded my MAC OSX computer to JRE 1.4.1_2. I have noticed a significant performance difference from 1.4.0. My program has a JTable with a scroll pane viewport. The table typically contains around 800 rows. When I try to scroll between rows (either using the arrows or slider) there is a lengthy (3 seconds+) lag before the window updates. In 1.4.0 on OSX and 1.4.1 on Win2k there is no problem and the scrolls are quick. Has anyone ran into a similar problem or can offer some insight into why this happens?
