ISPN-5023 Random Failues on *FactoryBeanTest in the Spring Modules

Remove the test cache manager factories and test the production ones
directly.
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
