javasnoop

Intercept Java applications locally
Normally, without access to the original source code, testing the security of a Java client is unpredictable at best and unrealistic at worst. With access the original source, you can run a simple Java program and attach a debugger to it remotely, stepping through code and changing variables where needed. Doing the same with an applet is a little bit more difficult. JavaSnoop attempts to solve this problem by allowing you attach to an existing process (like a debugger) and instantly begin tampering with method calls, run custom code, or just watch what’s happening on the system.
