------- Comment #5 from abalkiss at redhat dot com 2005-10-26 17:00 ------- An even more specific test case shows that the problem is in ScrollPaneLayout's preferredLayoutSize method.
***TESTCASE*** import java.awt.*; import javax.swing.*; class Test { public static void main(String[] args) { String[] items = { "Item1", "Item2", "Item3", "Item4", "Item5", "Item6", "Item7", "Item8", "Item9", "Item10", "Item11" }; JList list = new JList(items); list.setPreferredSize(new Dimension(150, 150)); JScrollPane scroller = new JScrollPane(list); System.out.println (scroller.getLayout().preferredLayoutSize(scroller)); } } -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17360
