JarCheck by Canadian Mind Products

Check a Java jar to make sure all the javac -target versions of the class files are what you expect. It makes sure that a jar intended to run under an old 1.1 JVM contains no classes accidentally compiled with javac -target 1.5. This should catch classes normally compiled with target 1.1 that were accidentally compiled with 1.5 as a side effect of compiling some 1.5 class.

Janino by Arno Unkrig

Janino is a compiler that reads a Java expression, block, or source file, and generates Java bytecode that is loaded and executed directly. It is not intended to be a development tool, but an embedded compiler for run-time compilation purposes, such as expression evaluators or "server pages" engines like JSP.

Wassup by Canadian Mind Products

Wassup lets you know what is 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.
