(JAR) cache.
Procedure

running, exit by closing the browser window.

Panel icon. 
Run the following command: java_install_dir/jre/bin/ControlPanel
- In the Java Control
Panel's General panel, click the Settings button and the Delete Files
button. Select all the check boxes that contain references to Applications
and Applets. Click OK to clear the cache.
