Fixes: #2994

[jean-tissot]

Hello,
I don't know if this bug fix should be added to the changelog so I didn't add it. I can do it if necessary (is it a [Core] fix or a [Java] fix ?)

[mpkorstanje]

That's okay! It's a [Core] fix. The [Java] fix would be used for cucumber-java module. A bit confusing but we also had cucumber-scala, cucmber-groovy and a few others.

On review, I only had one small remark. Which was easy enough to fix along with the changelog.

So thanks for the PR! This allowed me to release the fix today.

Should be available once https://github.com/cucumber/cucumber-jvm/actions/runs/14960479934/job/42021698326 completes.

I saw your fix. Indeed, I didn't think of this to make bugs easier to find when the test fails.
Thanks for merging it!
