Hi All,
Bug : JDK- 6714836 <https://bugs.openjdk.java.net/browse/JDK-6714836> JDK 10 Webrev: http://cr.openjdk.java.net/~pkbalakr/Krishna/6714836/webrev00/ The issue is that when a text label is added to JRootPane and query the maximumLayoutSize, it is returning 0. The root cause is because, JRootPane decides to provide the Minimum width of Menubar (which in this case is 0) and the content pane (which contains the JLabel). Actually, it should return the maximum of the two, since that is what is the layout size needed. Thanks, Krishna
