This (in functions.cpp) looks wrong. You're creating an instance of

PyObject *PyErr_SetJavaError(jthrowable throwable)

PyObject *err = t_Throwable::wrapObject(Throwable(throwable));
PyErr_SetObject(PyExc_JavaError, err);
Py_DECREF(err);

No, this code gets python to raise an error of type JavaError whose
error argument is the actual java throwable instance, wrapped.
What you see is two layers of wrappers:
1. Throwable(throwable)
wraps a C++/JNI wrapper around the actual java throwable
2. t_Throwable::wrapObject(...)
wraps the CPython Throwable type around the C++/JNI wrapper so that
one can make calls on it from python (such as getJavaException())
Once can then call getJavaException() on that JavaError instance to retrieve
the java stack trace from the actual java throwable:
try:
java(blah)
except JavaError, e:
print e.getJavaException().printStackTrace()
Andi..
