@martinezpenya Thank you for reporting this issue.

Is the problem occurring outside Docker or within Docker? Or is is "just" happening after having installed Docker?

[martinezpenya]

It's happening after having installed Docker.
Before this it works great.

[flemming-n-larsen]

OK. This should be easy to reproduce. I will have a look. 👍

[flemming-n-larsen]

@martinezpenya I have just installed Docker Desktop on Windows 11 running on WSL 2, and I can reproduce the issue.
I don't know what causes it yet, but I will find out.

[martinezpenya]

You're Super! thank you for your time!

[flemming-n-larsen]

I discovered, that this "only" occurs for the Java bots, but not the .Net bots.
And the issue is within the Bot API for Java, when a bot needs to send a message to the server via its socket. The first message is "ready" when the bot is about to participate in the battle. The server waits for the signal from the bots, but times out as it does not receive a "ready" signal from the bots.

[martinezpenya]

If I can help you in any way, let mi know.

[flemming-n-larsen]

I found the bug in the Bot API for Java, and fixed it.
The fix will be available with the next version of Robocode coming soon. 😊

[flemming-n-larsen]

Fixed with version 0.27.0, just released.

[flemming-n-larsen]

@martinezpenya Can you confirm the fix work for your students as well?

[martinezpenya]

Yes of course I will... My next class with them is on thursday, i'll come back and confirm that 0.27.0 solves the issue. Thank you so much!.

Hi @flemming-n-larsen everything works like a charm again. Thank you for your time.
Is there any way to support your work? buy-me-a-coffe or something like this?
Thank you!

[flemming-n-larsen]

@martinezpenya I am very happy to hear that! Thank you for reporting back! 😊

I haven't thought of buy-me-a-coffe. I will consider that.
Currently, I make Robocode for fun, and make sure to fix any issue that arise.
