This sounds like a problem with the certificate, or the SSL version. The JDK 21 release notes says:
security-libs/javax.net.ssl
➜ The Default TLS Diffie-Hellman Group Size Has Been Increased from 1024-bit to 2048-bit (JDK-8301700)
The JDK implementation of TLS 1.2 now uses a default Diffie Hellman keysize of 2048 bits when a TLS_DHE cipher suite is negotiated and either the client or server does not support FFDHE, which can negotiate a stronger keysize. The JDK TLS implementation supports FFDHE and it is enabled by default.
As a workaround, users can revert to the previous size by setting the jdk.tls.ephemeralDHKeySize system property to 1024 (at their own risk).
This change does not affect TLS 1.3 as the minimum DH group size is already 2048 bits.

The issue happens during the SSL connection handshake, there could be some difference between the server and client settings.
You can use -Djavax.net.debug=all -Dssl.debug=true Java options to debug.

I have the impression that the error I get from running the program is just part of a bigger issue. I'm more worried what I observe about open connections by the process. Also note, clearly this has little to do with JDK itself, issue starts manifesting when changing Jersey libraries from 2.40 to >=2.41.

For Jersey 2.43 when I enabled -Djavax.net.debug=all to test, I can see that for each of the POST requests from the program's loop new connection is getting open and SSL protocol negotiation occurs, which explains why execution takes significantly more time. Initially open connections get "abandoned" and would stale after a while, producing this kind of output:

With Jersey 2.40 this doesn't happen. For program one connection is open and reused for consequent requests execution, protocol negotiation occurs once before first request as expected. Is there anything changed in connections management with HttpUrlConnection after 2.40? Why would every time to make a request the new connection is needed, is that anticipated by the implementation for e.g. pooling?

There was quite some changes around SSL configuration and HttpUrlConnector happening in this commit: 73bdf5f
Not sure how to validate if that changeset introduced a problem with connections and open sockets that I observe.
