Work Description: kennknowles commented on issue #8104: [BEAM-6872] Add
hook for user-defined JVM initialization in workers
URL: https://github.com/apache/beam/pull/8104#issuecomment-481945621
Incidentally, the change to ReflectHelpers seems nice separately.
Deterministic ordering is good for reproducing issues. Though we should
consider the contents of the classpath to be nondeterministic because it is
fairly unpredictable. So it does _not_ allow one to actually reason about what
executes first. Only reproduce a run.
