You're right, the shared_ptr would take ownership against SWIG.
I don't see any easy solution to this one...

Another possibility would be to write a C++ payoff that adapts a Java
payoff. Its constructor would take a Java instance and store it, and its
operator() would use the foreign interface to call the corresponding
method in the Java instance. Kind of a home-made director. I don't know
if it would be possible to hide the mechanism so that it seems that the
Java class inherits from Payoff, though...
