The control(menus, buttons, ..etc) font of maple is ugly on linux jdk 1.4.x. So I tried to run maple on jdk 5.0 with swing.aatext=true option. I have installed crimson xml parser at {maple installation dir}/java directory. And I tried to start maple. But maple didn't start with next exception. Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: No such child: 0 at java.awt.Container.getComponent(Container.java:280) at com.maplesoft.mathdoc.components.dockingtools.WmiBorderSplitPane$DockContainer.(Unknown Source) at com.maplesoft.mathdoc.components.dockingtools.WmiBorderSplitPane.addAtLocation(Unknown Source)
