Hello, Volodymir

The bug you reported is still there on macOS:
jetty/jetty.project#12390

So I have updated your test case to the latest Jetty version

Please consider merging my PR

Hi Alexander,
Thank you I merged the MR.

Did I get it right that you can reproduce this bug in Safari using MacOS Sequoia 15.0.1 and Safari 18.0.1?

I'm still on MacOS Sonoma 14.6.1 with Safari 17.6, and it works fine for me. I followed the steps in the gif you provided and had no errors neither in the browser nor in Jetty, all messages arrive successfully.
(I will probably update MacOS to Sequoia and retest)

Thanks, Volodymir, yes, unfortunately the bug is there, here an Edge browser screenshot on my macOS Sequoia, running your sandbox app:

And also Firefox:

And Safari:

(I cannot try Google Chrome though, do not want to install it at my devices).

And the animated screenshot.gif - I captured it on Windows, that is why it works fine.

Interesting, I think this is something different.

The issue that I reported a while ago to Webkit (that bug in Safari) was only reproduced in Safari 13 (while working fine in other browsers) and with any websocket server (not just Jetty)

Now, I updated my laptop to MacOS Sequoia and I'm not able to reproduce this unknown opcode issue locally, I tried Safari 18.01 and Firefox 131.0.3. I have Macbook M1 Pro Sequoia 15.0.1

Update: this new issue on macOS might be caused by "parental controls" or "screen time", please see the discussion at jetty/jetty.project#12390
