It really depends on what you need, and how tight your integration needs to be.

Do you really need it to be jython?  Or could you use CPython?  Then the C++ integration is pretty easy.

If the tests need to exercise Java code, maybe JPE (http://sourceforge.net/projects/jpe) would let you write the tests in CPython & invoke the Java code that way.

Do you really need to write the verification process in C++?  Use Jython for that instead...

You can also have the C++ code use CORBA or a socket, and have the jython process connect back to the C++ server.

And worst case (?), you can always write C++ code to the Java Native Interface (JNI)...
