This is needed since the optimizer is based on OptaPlanner which uses all the memory it can get for optimizations. To the point this is either something going wrong in the installation or an access issue. Access can be caused due to root certificate not trusted by the browser. If you use wget https://ovirt.optimizer:8080/ovirt-optimizer/result/ do you get an issue / warning on unknown certificate?
