Hi everybody, In the next Oxygen version (version 18.1, this Autumn) we plan to abandon support for Java 1.6 and offer support only for Java 1.8 or newer. This means that you will no longer be able to run Oxygen using Java 1.6. Plugins and add ons compiled with Java 1.6 should work without any problem. If anybody has customization problems with our decision please tell us. Regards, Radu Radu Coravu <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com
