I get an error in my JRE when i try to optimize a large deployment problem using z3 JAVA-API and opt.priority box parameter. This problem doesnt occur, when I am searching for pareto fronts though. (i my example i use 3 contradicting criteria)
The following message i get in my eclipse console:
!MESSAGE [Z3] solving problem with parameters (params priority box timeout 10000)

This dicussion board is not in use anymore as Z3 has moved to GitHub. Could you please try to reproduce the error using the latest master branch source code from GitHub and, if it still exists, submit a new issue in our new issue tracker? Thanks!
