64 bit operating system
The Servoy Application Server supports 64 bit operating systems. To run Servoy on 64 bit, a 64 bit version of the Java Standard Edition Runtime Environment 5.0 or higher is required.
Issues have been reported when trying to run Servoy (either the Application Server, Servoy Developer or Smart Clients) using OpenJDK. For now it's advised to use ssun/Oracle JRE distributions instead.
