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.

Summary: NullPointerException in tomcatjss searching for attribute "clientauth"
Product: Red Hat Enterprise Linux 6 Reporter: Matthew Harmsen <mharmsen>
Component: tomcatjssAssignee: Christina Fu <cfu>
Status: CLOSED ERRATA QA Contact: Asha Akkiangady <aakkiang>
Severity: unspecified Docs Contact:
Priority: unspecified    
Version: 6.7CC: aakkiang, cfu, edewata, gsterlin, jdennis, mharmsen, nkinder, rpattath
Target Milestone: rc   
Target Release: ---   
Hardware: Unspecified   
OS: Unspecified   
Whiteboard:
Fixed In Version: tomcatjss-2.1.0-4.el6 Doc Type: Bug Fix
Doc Text:
Previously, the init() function in tomcatjss looked for the clientauth attribute which was not present. As a consequence, Tomcat returned NullPointerException in init() on startup, and in addition, some properties, such as enableOSCP and properties for enabling certain SSL ciphers, were not called. A patch has been applied to fix this problem. As a result, NullPointerException no longer occurs in the described situation, and the mentioned properties are called as expected.

Verification steps for the bug:

1. pkicreate CA and configure it
2. Check if "clientauth" exist in server.xml file, it should not exist
3. enable ocsp and set debug=true in server.xml file
