SimpleAliasRegistry misses log out in case of bean override [SPR-16871]

[spring-projects-issues]

Michael Decker opened SPR-16871 and commented

As we realized in Non unique bean producer method names are not invoked #13252, org.springframework.core.SimpleAliasRegistry.registerAlias(String, String) does not have any log output, if a bean is overridden, only an exception:

if (!allowAliasOverriding()) {
    throw new IllegalStateException("Cannot register alias '" + alias + "' for name '" +
            name + "': It is already registered for name '" + registeredName + "'.");
}

But these implementation does have a log output, if they override a bean:

org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader: INFO
org.springframework.beans.factory.support.DefaultSingletonBeanRegistry: INFO
org.springframework.beans.factory.support.FactoryBeanRegistrySupport: INFO
org.springframework.beans.factory.support.AbstractBeanFactory: INFO
org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory: INFO
org.springframework.beans.factory.support.DefaultListableBeanFactory: INFO

Perhaps it's even possible to have a common approach to log this. For example org.springframework.boot.autoconfigure.logging.ConditionEvaluationReportLoggingListener: DEBUG is a great help to understand auto configuration conditional issues. Something similar for such an issue would be great.
