1.2.8 Spacewalk Fails to Install Due to the slf4j Package Being Installed

In some circumstances, the Spacewalk installation can fail if the slf4j (Simple Logging Facade for Java) package is installed. The workaround is to remove the slf4j package. Be aware that Eclipse depends on this package, so you either have to uninstall Eclipse or remove the package with the rpm -e --nodeps slf4j command.
