- Please clear the Java(javaws -uninstall) and browser cache.
- Install the latest JavaFX runtime from hudson.
- Build the Ensemble app in ga-samples (clean->jar->web->deploy) and then bring up in applet mode (run index.html)
- Goto High lights , Run the Advanced Media , drag the timeline fast and try to switch to other samples like Candle chart etc extremely fast , at a point App does not accept Mouse inputs, until you refresh the page in browser. The following Exception is thrown , the applet and Java freezes (except the browser).
