org.opentripplanner.routing.core.StateEditor.makeState()
Why can a state editor only be used once? If you modify some component of state with and editor, use the editor to create a new state, and then make more modifications, these modifications will be applied to the previously created state. Reusing the state editor to make several states would modify an existing state somewhere earlier in the search, messing up the shortest path tree.
