Sessions randomly stuck about moon HOT 4 OPEN

@alex-buyanov is your Java code finishing its work? Moon closes Playwright sessions only when respective web-socket connection from your code is closed. If your code is stuck, then Moon session will be stuck too until you stop this code.

Nope. That's exactly the problem: a random test (or a couple of them) just get stuck during interactions between Playwright and Moon indefinitely.

I suspect that there is some kind of clash between TestNG threading model, Playwright Java and Moon. And I have no idea how to troubleshoot this :D

Running tests sequentially (non-parallel) eliminates the issue, but that's not a solution. Running tests without Moon also helps, but this is not a solution either.

I thought maybe somebody else have seen such an issue, but Google has failed me.

@alex-buyanov what is the version of playwright-java library and what playwright version do you request in Moon URL? Both versions should match.

I use Playwright 1.38.0 as of now. And I request the same version from Moon: I made sure versions are the same by checking the test code + actually looking at Moon's GUI (sessions have labels with Playwright version). Everything matches.

I also tried using older versions of Playwright, but that did not have any effect.
