RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #1052417 +++

This was discovered when debug is turned on.  

tomcatjss always throws NullPointerException in its init() function when starting up. Investigation shows that it's looking for the attribute "clientauth" (all lower case) and by default (in server.xml) if you don't have it, it does not handle it but instead let it fall through. 
This resulted in important things not be called such as
* enableOCSP
* eanble certain SSL ciphers

Testing suggestion:
To test this bug fix, here is one suggestion:
in server.xml
make sure "clientauth" (all lower case) is not there (which would cause NullPointerException without this fix)
make debug="true"
enable ocsp (follow the instruction in the server.xml)

restart server and you will see from /tmp/tomcatjss.log that
1. the ocsp is enabled etc. and
2. should not see any NullPointerException.

Or, you can go all out and test to see of ocsp is indeed working ... but I think observing the /tmp/tomcatjss.log should be sufficient.

Verified by executing the steps described in comment 2.
