I printed for SDFWithLifecycle in SplittableDoFnTest every call to the id of
the thread and the call to the method. Take a look at this commit
https://github.com/iemejia/beam/commit/75d8279858f2f4f0cd35af7a117ddb7ae7eb1e3a
This produces this output:

> Direct runner incorrect lifecycle, @SplitRestriction should execute after

> Key: BEAM-4016
> URL: https://issues.apache.org/jira/browse/BEAM-4016
> Project: Beam
> Issue Type: Bug
> Components: runner-direct
> Affects Versions: 2.4.0
> Reporter: Ismaël Mejía
> Assignee: Thomas Groh
> Priority: Major
> Attachments: sdf-splitrestriction-lifeycle-test.patch
>
>
> The method annotated with @SplitRestriction is the method where we can define
> the RestrictionTrackers (splits) in advance in a SDF. It makes sense to
> execute this after the @Setup method given that usually connections are
> established at Setup and can be used to ask the different data stores about
> the partitioning strategy. I added a test for this in the
> SplittableDoFnTest.SDFWithLifecycle test.
