I solve many subproblems, one after another. The post process is working fine and All values are correct and transferred properly. Then at one single subproblem following error message occurs (however: the problem could be solved and the data is transferred completely to the SQL database):

### UNEXPECTED UNKNOWN ERROR ...
java.lang.RuntimeException: internal error (Please notify IBM)
    at ilog.opl.opl_lang_wrapJNI.IloOplModel_postProcess(Native Method)
    at ilog.opl.IloOplModel.postProcess(IloOplModel.java:612)

For information: I use opl *.mod and *.dat files. The solving process is controlled with Java. I use both packages opl.jar and cplex.jar.

Has anybody an idea?

Thanks in advance

Regards

The first I would try is to catch this exception and check if it contains further information, like a nested exception, for example.

Moreover, since this is OPL I suggest to post the question on the OPL Forum.
