NullPointerException in Parser Constructor
Created by: Kleanthi
I am doing a test for HeliosPlanner and I am creating a plan that has a null measure expression in its filtering instruction (aka filter without condition but threshold only). Helios is trying to find get costs for this filtering instruction by finding the metric(s) in the measure expression and therefore, a function in Helios creates a Parser instance. I have fixed Helios to handle LS with filtering instructions with null measure expressions but that issue could also be raised somewhere else i.e. when someone gives an empty LS as input.
