Why does the 'yum update' command fail with a conflict between the packages "apache-commons-codec" and "jakarta-commons-codec"?

Issue

• Command yum update fails with following conflict errors.

yum --exclude=man-pages-3.22-20.el6.noarch update
Will result into:
Transaction Check Error:
  file /usr/share/java/commons-codec.jar conflicts between attempted installs of apache-commons-codec-1.7-2.el6_3.x86_64 and jakarta-commons-codec-0:1.3-11.7.el6.x86_64

• It complains about a conflict between packages which are not installed.

[root@hostname ~]# rpm -qa |grep  jakarta-commons-codec
