If you have deployed a Foundation application using Framework 2.1 and have created a desktop shortcut from java webstart then the desktop short cuts will no longer work if Java 1.6 is installed.


Foundation applications built with Framework 2.1 still require java 1.5 in order for them to run. But if you have Java 1.6 installed desktop shortcuts will use 1.6 be default, causing a runtime exception.


Currently, there is no way to use the desktop shortcut, but if you open javaws from within the original Java 1.5  bin directory and run the application from there it will load java 1.5 and the application will run correctly.
