Re: Null Pointer Exception from Linux Debian version A little research revealed that the AWT-EventQueue-0 NullPointerException is the most common exception that occurs in Java and it is caused by passing a null value to a method when a valid object or value is expected. Pretty straight forward as the same happens in every programming language. From your report it seems to happen when Java is trying to retrieve a font from the system. ("at sun.awt.X11FontManager.getFileNameFromPlatformName(X11FontManager.java:174)") It seems that the FontManager couldn't retrieve a font (now null) for which it is trying to get the filename. You will have to check that you have all fonts installed correctly AND that they are accessible with Java. You can try starting Sweet Home 3D as root and see if the same problem occurs. If that works correctly it means that a 'normal' user can't find/retrieve the same fonts as root can. Disclaimer: I'm a professional developer but not in Java. This is just from reading the error message and my general programming knowledge. ---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |
