* TODO: This is temporary solution for the failure of IT mng-0471. When StartForkedExecutionMojo clones the
* project it really needs a deep copy of the model to make sure manipulations to the project/model during the
* forked execution don't pollute the main execution. It's not clear to me right now whether manipulations to
* the model itself should just be prohibited (say be means of UnsupportedOperationExceptions) and only have the
* project be mutable. If we allow model updates like in 2.x, the code below should better be replaced with the
* original cloning code from ModelUtils.
