[OS] CPLEX Error 1017: Not available for mixed-integer programs.

[Joe]

I tried to solve a pure ILP program with CPLEX and OSSolverService
(from trunk version one hour ago) but it is resulting in a crash. This
problem is computed successfully with cbc and symphony. Please find my
problem computesheet0-problem.osil in google "Files section".

OSSolverService's output :
----------------------------------------
Input String =  -solver cplex -osil computesheet0-problem.osil -osrl
computesheet0-problem.osrl
Call Text Extra
Call scan string
call ossslex
Found option:  -solver cplex
Found option:  computesheet0-problem.osil
Found option:  computesheet0-problem.osrl
done with call to ossslex
HERE ARE THE OPTION VALUES:
OSiL file = computesheet0-problem.osil
OSrL file = computesheet0-problem.osrl
Inside FileUtil:getFileAsString and calling inFile
Inside FileUtil:getFileAsString, file read put into ostringstream
Inside FileUtil:getFileAsString, convert to a string
