Constructors for beans created using createBean(type) in Spring cannot be updated

[Artur-]

If you create a bean using

getAutowireCapableBeanFactory().createBean(type)

then Spring will cache the constructors and maybe other info for the type. However, the check that HotswapAgent uses for clearing the cache:

HotswapAgent/plugin/hotswap-agent-spring-plugin/src/main/java/org/hotswap/agent/plugin/spring/reload/SpringBeanReload.java

Lines 326 to 330 in a86384c

	String[] names = beanFactory.getBeanNamesForType(clazz);
	// if the class is not spring bean or Factory Class, remove it
	if ((names == null || names.length == 0) && !isFactoryMethod(clazz)) {
	LOGGER.trace("the class '{}' is not spring bean or factory class", clazz.getName());
	iterator.remove();

will print the class '{}' is not spring bean or factory class and then leave the invalid cached info in place.

This happens e.g. for Vaadin @Route classes which are not explicitly marked as Spring beans

At least in the basic case, only the constructor gets cached in AutowiredAnnotationBeanPostProcessor.candidateConstructorsCache and removing it from there resolves the issue. Is this something SpringBeanReload should separately check? Seems overkill to run the whole doReload loop for this case - unless something else is cached somewhere else
