Subject	[platform-core-dev] java.lang.StackOverflowError in BundleLoader        with version 3.4rc3

I'm hoping someone can provide some feedback / insights
into the following issue i'm seeing.

I've been using the eclipse RCP platform successfully for a rather small
project with about 7 plugins and the required set of plugins for the IDE
application.  i've recently switched to 3.4rc3 from the latest 3.3
and i can't start my app anymore.  i'll admit, i've made some changes
to my code in the process, but i believe nothing "too fancy"
to cause an issue like this.  

i'm running on sun's JDK 1.6  on windows XP.  

all of my manifest files are error / warning free.  

i took a look at the source code, and noticed that the method addExportedProvidersFor
keeps track of the "visited" bundles, but it's re-entering itself
in such a way that the local variable "visited" isn't getting
propageted through the other methods.  

perhaps i have a circular plugin reference or something, but none of the
tooling is giving me any warnings of that, and i've been running successfully
on 3.3.

again, any insights into a potential problem would be apreciated.  

-Richard
