and not work, suggestion?

avoid using null layouts, pixel perfect layouts illusion within modern ui design. there many factors affect individual size of components, none of can control. swing designed work layout managers @ core, discarding these lead no end of issues , problems spend more , more time trying rectify

jscrollpane relies on layout manager api in order calculate preferred size of container showing , determine when view larger , should show scroll bars
