Hi @dholmes-ora, this is feasible, but in fact, the super class of VirtualMachine has already saved an unresolved pid(String) and corresponding getter method, so if we want to avoid re-parsing pid, we should save this parsed result in the parent class of the parent class of VirtualMachineImpl, and then modify the corresponding method, which seems to be beyond the scope of simple refactoring, so I hope avoiding re-parsing can be done by another PR
