I'll try their fix. My main concern is that I do not want to disable
TLSv1.3.
If you don't want to disable TLSv1.3, then you want:
<Connector ....
protocols="TLSv1.2,TLSv1.3"
/>
If BC is failing you, I'd want to find out if you really need BC.
That first link above seems to suggest that when using Tomcat you MUST
disable TLSv1.3. That seems odd. What version of BC are you using?
Search for .jar files with names like "bouncy".
Do you have the option to downgrade Java?
Have you tried disabling the RSASSA-PSS algorithm as per their
instructions? It seems ... far-fetched that would fix the problem, but
... okay.
Note that at some time in the past, Java 1.8 did not support TLSv1.3 and
lots of people who were stuck on Java 1.8 decided to switch to BC which
did have TLSv1.3 support. With that version of Java 1.8 (_281), you
should have native JDK support for TLSv1.3. Perhaps BC is not necessary
at all.

Lots of good information was provided.
This afternoon I plan to test the "sslProtocol" to "protocols" change in
our lower environments. I will reply back with any findings.
Thank you everyone for your responses.

Oh. You are using BouncyCastle. I've never tried to do that. I'm not
sure how well BC will work with Tomcat. We don't officially support
that configuration, but that doesn't mean we won't try to help.
This isn't a Tomcat issue but an interoperability issue between
BouncyCastle & OpenJDK.

Oh, great. Looks like a BC upgrade will fix the NPE. But possibly
something downstream will still fail...
Just to add my 2 cents here :
Per the problem posed in the very first email, we see the SSL/TLS issue
between Oracle JDK 8 and Tomcat 8.5
Environment:
OS: CentOS 7
Apache: apache-tomcat-8.5.65
Java: jdk1.8.0_281
Note that the following link - talks about issues between OpenJDK 11 and
BC.
https://bugs.openjdk.java.net/browse/JDK-8216039.
This morning's suggestion (about changing from "sslProtocol" to
"protocols" ) from Christopher Schultz, sounds promising, in that the
interaction between the Browser-clients and Tomcat 8.5.x server, will be
limited only to TLS1.2
Making this change, will preclude other old protocols - like TLS 1, TLS
11 etc in communication between the clients and the Tomcat server.
We will need tests after making the change to "protocols" attribute in
the HTTPS connector block.
In context of the above mentioned change -we may not need any editing of
"java.security" file contents (discussed last evening).
Thanks,
-Raghu
