Picking this up again.... thanks Luciano and Raymond for the suggestions. I found another approach. Though we may not have a full-blown extension point we can actually use the ResourceObjectFactory and its ResourceHost to accomplish this goal fairly easily.
I'd just need to add a ResourceHost field to JavaResourceImpl and change JavaImplementationProvider to honor this field when constructing my ResourceObjectFactory (and move a few classes from impl-java-runtime to impl-java maybe). If there are no objections I'll open a JIRA and post some code... Thanks, Scott
