[Ipopt] java ipopt dispose

[Stefan Vigerske]

Hi,

probably a wrong use of smart pointers in the jipopt.
The source in Java_org_coinor_Ipopt_OptimizeTNLP looks to me as if the 
object behind the ipopt member in the Ipopt class will already be 
deleted at the end of Java_org_coinor_Ipopt_OptimizeTNLP.

Does it work if you comment out the line
   delete problem;
in jipopt.cpp:Java_org_coinor_Ipopt_FreeIpoptProblem ?
