[Pljava-dev] Returning complex complex objects

Hi Krzysztof,

This is not really anything to worry about. The TupleDescs are freed
in a finalizer which will be run "sometime in the future." There is a
chance it's using the wrong free function and if so I expect to have
that patched before X-mas.

I do feel it's a bit "unprofessional" to have such warnings as it
gives the impression there may be a bug somewhere. It is possible to
keep track of the TupleDesc objecs in a separate data structure and
dispose of them when the Java function returns. I can provide a patch
for this in the near future if there is any wish for it. Let me know.
