[Failing Test]: Pylint failed when hypothesis > 6.148.3 is used

[shunping]

What happened?

The workflow https://github.com/apache/beam/actions/workflows/beam_PreCommit_PythonLint.yml failed recently due to a recent update on hypothesis.

The first failure:
https://github.com/apache/beam/actions/runs/19810292801

The last success:
https://github.com/apache/beam/actions/runs/19804782905

The only difference of the above runs is the version hypothesis. The failure run was on 6.148.4, while the successful one was on 6.148.3.

Error message:

************* Module apache_beam.coders.coders_property_based_test
apache_beam/coders/coders_property_based_test.py:132:4: W0101: Unreachable code (unreachable)

apache_beam/coders/coders_property_based_test.py:136:4: W0101: Unreachable code (unreachable)

Still unsure about if it is a hypothesis regression or a pylint bug yet.

This looks more like a Pylint false positive rather than a Hypothesis regression. It has been reported in the pylint repo recently:

pylint-dev/pylint#10785
