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 of problem:

There is a name conflict with java-1.6.0-sun 64 and 32 bit versions which does not allow both to be installed on the same system.

Similarly, the java-1.6.0-sun-plugin packages have a conflict with two pixmap files.


Version-Release number of selected component (if applicable):

java-1.6.0-sun-1.6.0.21-1jpp.2.el6

How reproducible:

yum install sun-1.6.0-sun.i686

ERROR with rpm_check_debug vs depsolve:
java-1.6.0-sun(x86-64) = 1:1.6.0.21-1jpp.4.el6 is needed by (installed) java-1.6.0-sun-plugin-1:1.6.0.21-1jpp.4.el6.x86_64

yum install sun-1.6.0-sun-plugin.i686

Steps to Reproduce:
1. Try to install java-1.6.0-sun and java-1.6.0-sun-plugin i686 versions on a x32_64 machine using yum 
  
Actual results:
Conflicts arise because of the name and conflicting contents of the -plugin package.

Expected results:
Both versions should be able to install on the same machine in parallel

Additional info:

Although there are both i686 and x86_64 java-1.6.0-sun base packages in the x86_64 tree, we ship only the 64bit plugin there. So installing the i686 plugin is basically unsupported on x86_64.

RHEL-6 x86_64 does not ship a 32-bit Firefox. Without it, the Sun/Oracle 32-bit plugin will not work. Therefore not shipping the 32-bit plugin x86_64 is the right thing to do. 

Attempting to force install it from the 32-bit rhel-6 repo can have unpredictable consequences (such as the existing 64-bit alternative breaking) and it is best avoided.
