Description

We had a user reporting non-deterministic NPE's here - https://github.com/apache/metron/blob/master/metron-stellar/stellar-common/src/main/java/org/apache/metron/stellar/dsl/functions/resolver/ClasspathFunctionResolver.java#L250. The purpose of this ticket is to more gracefully handle the NPE and add some additional debugging information to better track down the source of this issue should it come up again.
