OSGI classloader DTMManager

Question

I am converting an existing application over to OSGI and have ran in to the following issue:

As you can see, it is continually trying to load the DTMManager over and over again. I have made it through the rest of the errors in my logs and this is the final thing that I see. I have tried many things to get this to load and from what I have read it should be loaded by the parent class loader from the bootloader as per the config file. I see the entry for org.osgi.framework.bootdelegation and it does include those packages:

org.osgi.framework.bootdelegation = \
 org.eclipse.virgo.osgi.extensions.*,\
 org.eclipse.virgo.osgi.launcher.*,\
 org.eclipse.virgo.kernel.authentication,\
 com.sun.*,\
 javax.xml.*,\
 org.apache.xerces.jaxp.*,\
 org.w3c.*,\
 org.xml.*,\
 sun.*

Any help would be awesome!

Thanks
