ProgrammaticallyAddedProcessBeanAttributesTest counts the number of ProcessBeanAttributes events and expects the count to be 0 in the end (That would suggest that no PBA was fired for built-in beans nor beans added via AfterBeanDiscovery.addBean()). However this is incorrect since an application server may bundle extensions that register (synthetic) annotated types. These are not built-in beans per definition and therefore they affect the counter in the test.
