This dialog allows you to specify a list of preferred JRE versions when running your Java Product.
To add a new version, type it in the top edit box and press thebutton. To remove a version, select one and press the button. Use to empty the list. Press when you are done or to undo your changes.
The versions are matched by integer fields, starting from the first one. The missing fields match everything, meaning that 1.4 matches 1.4.1 and 1.4.2_01, while 1.4.0 only matches 1.4.0 or 1.4.0_02. If more versions are matched, the highest one is selected.
