<p>I already replied to Norman directly (because apparently I cannot
seem to find my Reply-all button before my morning caffeine!). It
does look quite a bit like <span class="">8241248 and that issue
is in my bug queue. I haven't started work on it yet, but now
that Norman has provided me some links to a reproducer I can
give it a spin and see if I can make the bug happen locally
(Thanks Norman!)<br>

<div class="">Unfortunately I don’t have a reproducer
which uses the JDK only here but I can reproduce this
with Netty that uses OpenSSL on the client side and
the JDK SSLEngine on the server side.</div>
<div class="">I can reproduce this with the latest JDK11
release but can't with JDK15. Also what makes me
believe it may be a concurrency bug is that only some
handshakes fail. Like 70 out of 2600 fail.</div>
<div class=""><br class="">
</div>
<div class="">While the reproducer also involves netty I
am wondering if you would still be interested in it ?
It should be quite straight forward to run locally for
you.</div>
