Mark Paluch opened SPR-15841 and commented

BeanDefinitionBuilder declares setInitMethodName, setDestroyMethodName and setScope methods that do not accept @Nullable arguments.

Forwarding values from a given BeanDefinition requires warning suppression or additional code to satisfy null checks:

class CassandraCqlClusterParser extends AbstractBeanDefinitionParser {

	@Override
	protected AbstractBeanDefinition parseInternal(Element element, ParserContext parserContext) {

		BeanDefinitionBuilder builder = …;

		if (parserContext.isNested()) {

			// warning is raised in the next line
			builder.setScope(parserContext.getContainingBeanDefinition().getScope());
		}

		return …;
	}
}

Affects: 5.0 RC3
