Hi, It looks like for some interesting reasons the configadmin and the scr bundles bind to different exported Configuration Admin API packages. I would assume, that this is an issue of multiple bundles exporting the same package, probably at different versions and thus causing this mishap.
The explanation for the difference of Java 5 and Java 6 I have is, that there seems to be some difference in timing of bundle loading and starting. Maybe the bundles are internally prepared in a Set or Map and then iterated to install and start. Using the Web Console you should be able to tell to which bundle the scr and configadmin bundles wire to get the Configuration Admin API. On the other hand, this is interesting because the SCR bundle should not get the ConfigurationAdmin service if the API does not match. Strange.
