What container are you starting, which ports does it expose? Or doesn't that matter (e.g. just running `docker run hello-world` already causes the problem)?

Very strange, no idea what would be causing this. Do you run Firefox on the same machine as FitNesse? Does a remote client experience the same problem? Does the same...

Not that I am aware of. But you could, of course, add the junit-vintage jar as a dependency which allows jUnit 5 to run jUnit 4 tests. With maven that...

I believe [`Extension`](https://junit.org/junit5/docs/5.0.1/api/org/junit/jupiter/api/extension/Extension.html) is indeed a marker interface, but I believe one has to implement one of the the sub-interfaces to actually do something during a test run. The `FitNesseRunner`...

@oliverkuntze unfortunately a FitNesse is currently not thread safe, so a single JVM process cannot run multiple tests in parallel (see https://github.com/unclebob/fitnesse/issues/806), so we cannot (yet) support a single FitNesseRunner...

@oliverkuntze for the XML filename issue I have a workaround when using Maven, I assume something similar can be achieved for Gradle: I use [my own listener](https://github.com/fhoeben/hsac-fitnesse-fixtures/blob/master/src/main/java/nl/hsac/fitnesse/junit/JUnitXMLPerPageListener.java) to generate a...

@oliverkuntze my listener predates the partitioner by quite a bit. The problem already existed when you used manual partitioning using tags. I always add my fixtures project to test sets...

@oliverkuntze if you could make a PR that would be great. Does you listener work on jUnit events or directly on FitNesse events? I always find myself getting confused as...

@oliverkuntze let's move this discussion out of this issue an into a PR (that will also make it clearer what classes we are talking about). Depending on how many classes...

As far as I know there's no way to escape a comma in this converter. (But in your example I expect you get an array with 3 elements `"one`, `two`...
