to see if that is the case as that might give us more information about the issue and potentially

Looks like eagerly loading all the application's annotations and enums twice does the trick.
 The first time fails with the LinkageError and the second time works.

Currently performing some magic in debugger with evaluating expressions to get this accomplished.
 Not going to codify it just yet, but if we wanted this as a hack as an implemented workaround
we'd need to use ASM to scrape and get a list of all annotation and enum classes, put that
data in perhaps a gbean that is setup to load on app startup with a dependency on the app
classloader, then have that gbean do the double load.  The xbean-finder code doesn't currently
have the ability to list annotations and enums -- we'd have to add it or scrape again.

Hopefully we can find the real issue and not have to do that.
