* add delegation to `BeanDefinitionReaderUtils.generateBeanName(definition, parserContext.getRegistry(), parserContext.isNested())`
in the `AbstractBeanDefinitionParser#resolveId()` implementations when it is necessary.
* remove redundant `shouldGenerateId()` & `shouldGenerateIdAsFallback()` when they don't make sense.
* additional simple polishing in the affected classes.
* remove TODO & forced 'id' attribute from JpaOutboundGatewayTests-context.xml to check that this solution works as was booked.
