Work Description: kennknowles commented on issue #5597: [BEAM-4526]
Suppress immutability warning caused by LoadingCache in enum instance
URL: https://github.com/apache/beam/pull/5597#issuecomment-396707064
I'm just not a huge fan of using language constructs in this way, since enum
is an homage to lower-level languages where they are just primitive constants.
This might be the first time I disagree with Effective Java :-) but maybe I'm
just being curmudgeonly. I accept this as a new snazzy thing that might become
standard.
