How can I run my own java code in the JVM that I am debugging remotely with JDWP?

Question

As a penetration tester, I have come across an open JDWP port. I can connect to it with Eclipse and browse the threads and memory, but I don't have the source code for the application. I'd like to inject my own Java code, perhaps as an Exception handler, in order to return a shell. How can I modify the running/suspended Java application over JDWP, preferably using Eclipse as my debugger?

I found the answer to my question: JavaPayload by Michael 'mihi' Schierl lets you load Java payloads through JDWP, among others.
