When accessing bundles in the RuntimeArtifactModel (RAM) that have dependencies that cross in to the Kernel region a faux bundle is provided that represents the Kernel region. The RAM then tries to gather information on this fake bundle which causes a stacktrace in the logs, no exception is given out over the JMX interface.

To Reproduce:
Start up Virgo then use JConsole (or vsh or the admin console) to view a bundle with deps in the kernel region. Then go a browse the main log file and you will find the following stack trace.

Extra handling is needed for the new faux KernelRegionBundle.
