Spring Security and OSGi

I am trying to create a simple example using Spring Security 3.1.3 on Virgo 3.6.0.M03.
The example consists of 3 bundles:
- security bundle configuring and publishing an AuthenticationManager
- helloSecurity bundle publishing a secured helloWorld method. It references the AuthenticationManager and injects it in global-method-security.
- helloSecurityConsumer bundle referencing the helloSecurity IF and calling the secured helloWorld method.

Bundle statup and wiring work properly, but once helloSecurityConsumer calls the secured method the following exception is thrown:

Code:

GlobalMethodSecurityBeanDefinitionParser attempts to use the referenced AuthenticationManager and has a problem converting the Proxy around the OSGi refeternce to a ProviderManager.
Debugging shows the Proxy (a jdkDynamicAopProxy) is indeed a proxy around the ProviderManager class and has all the relevant interfaces.
Is there a working configuration to achieve what I am trying to do?
I am attaching the 3 projects, unfortunately the pom files will need some modifications to compile without the parent build.

This turned out to be a bug. I have raised https://jira.springsource.org/browse/SEC-2087
