Java 6 SE update 10 and the Great Java Cache Viewer - The Dream Team

Java 6 SE update 10 comes with many non-functional (often not directly visible enhancements). The Cache Viewer is an exception - it is a visual tool which allows the management of all installed webstart and JNLP-installed applets (both were unified) applications. This tool can be launched with [JAVA_HOME]/bin/javaws -viewer. The Java Cache Viewer is able to:

list all installed WebStart (and probably cached Applet) applications
deinstall existing application
reinstall a deinstalled application
display the JNLP of a particular application
directly (offline/online) execute the application
install shortcuts on the desktop (tested on Vista)
display the cache size

The Cache Viewer was already available in the JDK 1.6 update < 10, but it is especially usable for the management of new Java 6 u10 applets / webstart apps. I use it mainly to find a "lost" application :-).
