Simpleforwarding cache synch doesn't work

- When Simple forwarding cache syncs the HostNodePair it will cause
exceptions in the clustering services because cannot find HostNodePair
class, this is simply because the Export-Package of SimpleForwarding
bundle was exporting no packages and this was due to the mis-spelling
in the package name.
