markt pushed a commit to branch 10.0.x
in repository https://gitbox.apache.org/repos/asf/tomcat.git
The following commit(s) were added to refs/heads/10.0.x by this push:

0d5fdc3 is described below
commit 0d5fdc30f379c060fe5ccb7301231152f4341f16
Author: Mark Thomas <ma...@apache.org>
AuthorDate: Thu Mar 24 16:19:09 2022 +0000
Log a warning for CLIENT-CERT + JSSE TLS 1.3 as PHA is not supported
CLIENT-CERT requires post-handshake authentication (PHA) to work with
TLS 1.3 but the JSSE TLS 1.3 implementation does not support PHA.
