zabetak opened a new pull request #1090: [CALCITE-2897] Reduce expensive calls to Class#getSimpleName
URL: https://github.com/apache/calcite/pull/1090
 
 
   1. Replace rule.getClass().getSimpleName() with rule.toString():
   (i) It conforms to the API VolcanoPlannerPhaseRuleMappingInitializer;
   (ii) It is safer to use when the same rule class has many instances;
   (iii) It is much more efficient.
   2. Precompute the class name for Boxed primitives and use where necessary.
   3. Remove Types#boxClassName since it is slightly redundant.
