The no arg constructor doesn't really serve any purpose. I will change `fromGlobalConfig` to a constructor (should have done this in the first place). The NPE comes from Caffeine code. As long as we're not passing in null values to the cache builder it's not an issue. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
