Thanks Chris.
The TLS 1.3 problem happens for all TC versions. It looks to me as a
test limitation. We check, whether TLS 1.3 support is present in the JVM
via "SSLContext.getInstance(Constants.SSL_PROTO_TLSv1_3)". If so, we do
the TLS1.3 test, configure TC to use TLS 1.3 but use a default
HttpURLConnection in TomcatBaseTest.java without any specific TLS setup.
But in 1.8.0_272 although TLS 1.3 is available, it is disabled by
default for clients. So the test fails.
We could probably in TestClientCertTls13 replace the default
SSLSocketFactory in HttpsURLConnection by one that wraps the original
default one but also sets TLS 1.3 as enabled on any socket it creates.
That way we would "fix" behavior in TomcatBaseTest without the need of
adding more parameters to the calls there.
Concerning the problem observed on RHEL 8 only with Red Hat provided
OpenJDK: after upgrading to their latest Java 11 patch level, the
problems for Java 11 are gone. After upgrading to their latest Java
1.8.0_272, I can still see the problems there. No problem for the same
test when using Adopt or Zulu 1.8.0_272 and also not for original
OpenJDK 1.8.0_272. I can see a difference in supported ciphers and I
expect the reason to be there:
< RedHat 1.8.0_272
> RedHat 11 and all non Red Hat Java 1.8.0_272
< SSL_RSA_WITH_NULL_SHA
< TLS_ECDHE_ECDSA_WITH_NULL_SHA
< TLS_ECDHE_RSA_WITH_NULL_SHA
< TLS_RSA_WITH_NULL_SHA256

> TLS_DHE_DSS_WITH_AES_256_CBC_SHA256

> TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256
> TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256
> TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA
> TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384
> TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384
> TLS_ECDH_RSA_WITH_AES_128_CBC_SHA
> TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256
> TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256

> TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384
> TLS_ECDH_RSA_WITH_AES_256_GCM_SHA384
This seems to be a limitation specific to the RedHat JDK 1.8.0_272.

Rainer,
I recently had some weirdness with TLS connections as well. Please see
my post titled "SSLException after Java upgrade".
"Recently", Java moved certain EC curves to the attic and won't
handshake properly anymore.
Another investigation of my own product running into a network exception
that hadn't been generated before. It looks like a change to the JRE.
https://bugs.openjdk.java.net/browse/JDK-8215102
This was initially reported as an error with MySQL connections but it
appears that the driver's involvement was unnecessary. Please see
Severin Gehwolf's comments from 2019-01-25.
I'm not sure if either of these issues are related to yours, but I
wanted to make suer you were aware of them.
Hope that helps,

Hi all,
I tested TC 7.0.106 plus a few patches from git with a variety of JVMs
on a few Linux distributions. I observed:
- org.apache.tomcat.util.net.TestClientCertTls13 now fails for Java
1.8.0_272 be it OpenJDK, Adopt or Zulu on all Linux distros I tested.
TLSv1.3 was backported to Java 8 in the recently released Patchlevel
272 and is enabled on the server side by default, but not on the
client side. The test succeeds as soon as I add
"-Djdk.tls.client.protocols=TLSv1.3". I guess correct TLS1.3 detection
during test gets moire and more complicated ...
- Only on RHEL 8 (e.g. not RHEL 6 or 7) and only with Red Hat provided
Java 1.8.0 and 11 (but not for other distributions of Java 1.8.0 or
11), lots of TLS tests fail. For example TestSsl test testSimpleSsl
show the following when started with -Djavax.net.debug=all und Red Hat

Dont know whether the error in the finalizer really is the root cause
and it might well be a JDK error, but I at least wanted to provide the
info here.
