5.303. slf4j

Updated slf4j packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The Simple Logging Facade (SLF4J) for Java serves as a simple facade for various logging APIs allowing the end-user to plug in the desired implementation at deployment time.

Bug Fix

BZ#831933, BZ#828644
The slf4j packages contained a non-functional dummy API implementation which was not supposed to be used. This dummy implementation was always selected instead of other implementations and UnsupportedOperationException was thrown. The dummy API implementation has been removed, so that user-supplied implementation is now always chosen, and slf4j works as expected.
All users of slf4j are advised to upgrade to these updated packages, which fix this bug.
