Overview
What is CMP Wassup?
CMP Wassup : A lightweight application that enables you to find out details about your installed Java version, the vendor, specification version and so on
In depth
A closer look at CMP Wassup
CMP Wassup is a small applet that lets you know what's up with your Java environment. It will tell you the System Properties, as many as the Security system will let you peek at. This includes such things as which JVM is running, which version of Java, which vendor. It may be run as either an Applet or an application.When you run Wassup as an application it shows you considerably more information. The Java sandbox considers it a security risk to reveal that information to an Applet. As an application, you can see all the possible System Properties. When you run as an unsigned Applet, your view is much more limited. If you OK the Java sandbox security override, it will let you view the restricted properties.As a heads-up, for this applet to work, you must click grant/accept/always run on this site/I accept the risk to give it permission to read the restricted system properties. If you refuse to grant permission, the program may crash with an inscrutable stack dump on the console complaining about AccessController.checkPermission.For more issue-avoiding advice, go to the developers page.
