Json Formatter in 1.1.3 giving Array Out of Bounds exception

When I run a test with a Before Hook, I am getting an Array out of Bounds exception.

java.lang.ArrayIndexOutOfBoundsException: -1

    at gherkin.formatter.JSONFormatter.getFeatureElement(JSONFormatter.java:199)

The same feature and hook worked with Cucumber JVM 1.1.1 and Cucumber JVM 1.1.2

When I remove the json format from the scenario, the scenario runs.

I suspect this is a regression introduced by ba049aa. Can you create a test that reproduces this?

I will try to create a test tonight.

I noticed that the commit you mentioned seemed to go into 1.1.2 which I can run without any issue. So I was thinking it was probably one of the commits in 1.1.3 that caused the regression....

#426

SInce this specifically dealt with the json formater I suspect it is the problem. If I do not use the json formater then the tests run fine and the html report looks good.

Thanks

The test has been adjusted to show the issue in this PR

#478

The JSONFormmater has no element to add the Before Hook to... since the senario has not beed added yet.

Moving format(formatter)

Before Move

@Override
    public void run(Formatter formatter, Reporter reporter, Runtime runtime) {
        runtime.buildBackendWorlds(reporter);

        runtime.runBeforeHooks(reporter, tagsAndInheritedTags());

        runBackground(formatter, reporter, runtime);
        format(formatter);
        runSteps(formatter, reporter, runtime);

        runtime.runAfterHooks(reporter, tagsAndInheritedTags());
        runtime.disposeBackendWorlds();
    }

After Move

@Override
    public void run(Formatter formatter, Reporter reporter, Runtime runtime) {
        runtime.buildBackendWorlds(reporter);
         format(formatter);
        runtime.runBeforeHooks(reporter, tagsAndInheritedTags());

        runBackground(formatter, reporter, runtime);

        runSteps(formatter, reporter, runtime);

        runtime.runAfterHooks(reporter, tagsAndInheritedTags());
        runtime.disposeBackendWorlds();
    }

in CucumberScenario.java.

This fixes the issue with the JSONFormatter but causes issue in the JUnit Reporter.

So it looks like one of the two will need to be updated to fix the issue.

This issue seems related to #447

@aslakhellesoy

I think we have the same issue at our place, @aslakhellesoy : does this PR fix the bug ?

I had to make a SNAPSHOT-build of cucumber-jvm/gherkin in order to fix our builds. But as we're using the Maven-Release-Plugin, which forbids making releases with SNAPSHOT-dependencies, we can't do legal releases anymore.

When will this bugfix go into a release?

This might be related to cucumber/gherkin#252 as well.

Isn't this fixed in 1.1.4 and/or 1.1.5-SNAPSHOT?

Yes, it is fixed in 1.1.4 (which is showed by the merge of #478).
