Hi,
Thanks for your message and interest in Java Security.
We are currently working on an implementation of Hybrid Key Exchange in
TLS 1.3 [1]. It will not be in JDK 25 as the release is entering
rampdown phase 1 soon.
Although we can't commit to a target release at this time, we hope to
deliver it in a timely manner after the RFC has been published.
Potential backports will be determined at a later date.

Hi,
I've been trying to find out when OpenJDK will have support for hybrid
key exchange in TLS 1.3.
I've found the corresponding issue: https://bugs.openjdk.org/browse/
JDK-8314323 <https://bugs.openjdk.org/browse/JDK-8314323>, but not able
to find any information on the status of this work, nor what OpenJDK
releases it targets.
Is this planned for OpenJDK 25? Are there considerations to back-port to
older releases?
