This was caused by the following:

public void logScenarioStart(Scenario scenario) {
scenario.write("Scenario: " + scenario.getName() + "\n");
}

This issue will be fixed when Cucumber-JVM is updated to use Gherkin v4 (#1035), until then do not use before hooks calling write together with the Json Formatter.

[brasmusson]

Now when #1035 has been merged, the 2.0.0-SNAPSHOT version from the master branch (with the groupId io.cucumber), the Json Formatter handles writes from before hooks correctly.
