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:
Japanese, Chinese, Korean and possibly other fonts are not displayed properly inside Java applications on RHEL6.

The fontconfig files under /usr/lib/jvm/java-1.6.0-sun/jre/lib/ are not updated in order to reflect the current font situation in RHEL6.

It seems that the fontconfig files have been inherited from RHEL5 without modification and rely on packages such as fonts-japanese, fonts-chinese etc. which are no longer included in RHEL6. 
Instead, RHEL6 now provides fonts such as vlgothic, wqy-zenhei-fonts and so on.

The java package needs to be fixed in order to provide support for such fonts.


Version-Release number of selected component (if applicable):
java-1.6.0-sun-1.6.0.21-1jpp.4.el6.x86_64


How reproducible:
Open a java applet which contains Japanese characters.
For example: http://www.asahi-net.or.jp/~ik2r-myr/kanji/kanji1pa.htm


Steps to Reproduce:
1. Confirm that the vlgothic-fonts is installed. 
2. Open Firefox and go to http://www.asahi-net.or.jp/~ik2r-myr/kanji/kanji1pa.htm
3. Observe the Japanese characters inside the applet
  

Actual results:
Japanese characters are shown as rectangles.


Expected results:
They should be displayed as normal.


Additional info:

Oracle is not supporting those fonts. To solve it, we can just recommend to swap to openjdk where is in our powers to fix it.
