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.

Description Mike Millson 2022-06-23 19:33:16 UTC 
The following empty directories were deleted when updating from 1.8.0.282.b08-1.el7_9.x86_64 to 1.8.0.332.b09-1.el7_9.x86_64:
*/etc/krb5.conf.d
*/etc/cron.monthly
*/etc/cron.weekly

Something very unexpected is causing copy_jdk_configs_fixFiles to escape from /etc/java/<java-version>/ to /etc/ and identify and remove empty folders that are not associated with the java install.

Add checks to prevent the code from escaping /etc/java/<java-version>/.

I can confirm that providing rogue symlink to etc may lead to the cleaner script to leak out of /etc/java/nvr/configs
The fix should be to verify each deleted directory belongs to the RPMbeing deleted.  Bad consequence will be that the cleaner script was supposed to remove dangling leftovers after custom configs, this wil be gone, but still better then remove foregin dirs in /etc

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.

For information on the advisory (copy-jdk-configs can remove empty dirs in etc if rogue symlink is placed in jdk), and where to find the updated
files, follow the link below.

If the solution does not work for you, open a new bug report.
