Comments
EVALUATION Swing menu items don't use a layout manager to lay out components. Menu items do it themselves. So JMenuItem.setLayout() doesn't affect anything. However, you can set a layout manager for a menu. Really, there is a problem with JMenuItem.setHorizontalAlignment(). Now the horizontal alignment always should be LEADING, otherwise menu item components can be laid out in a wrong way. It will be fixed in the bounds of a fix for 6458123. A fix for 6458123 is almost done and I believe it will be integrated into 6u4. So I close this bug as a duplicate of 6458123.
