The TransactionConfigurationProducer loads an extension configuration on demand using the BeforeSuite event. This behaviour appears to be insufficient when Aslak`s Brute Force Arquillian Suite Extension is in play, since the Suite Extension interferes the test case bootstrap process and enforces early usage of ARQ components.
As a suggestion for TX-ext to support such a constellation the configuration loading of transaction extension can be moved right into the phase where ConfigurationRegistrar loads configurations and notifies observers about available ArquillianDescriptors.
