Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

How reproducible:
Every startup
Steps to Reproduce:
1. Upgrade from 6.9.8 to 6.10.3
2. (re)Start Satellite with satellite-maintain [re]start
3. View /var/log/messages
Actual results:
WARNING lines for illegal reflective operation( and for synthetic methods, but those are a Candlepin issue)
Expected results:
No WARNING lines
Additional info:
Please ask
The warning messages do not have any functional impact and can be safely ignored.
You can reduce the warnings by using the --illegal-access=permit parameter (this will not be an option in Java 17+), permit the actions with no warning by adding the block from https://github.com/apache/tomcat/blob/7.0.x/bin/catalina.sh#L322 to your tomcat.conf, or avoid them completely by using Java version 6-8 instead with preference being the latter option because there were several enhancements made to Tomcat 7 regarding Java 9+ support that are not included in the RHEL version (https://tomcat.apache.org/tomcat-7.0-doc/changelog.html has more information).
