Oliver Drotbohm opened SPR-10993 and commented

If an ApplicationContext contains BeanDefinition instances for a type MyComponent<T> and you try to wire it to an injection point that explictly refers to a type parameter (e.g. MyComponent<String>) you currently get a NoSuchBeanDefinitionException.

Sorry for the crossed wires, but there's now a duplicate issue at #15632. It has a simple test-case attached, if you need it, otherwise go ahead and kill it.

DefaultListableBeanFactory performs a fallback check for autowire candidates now, which GenericTypeAwareAutowireCandidateResolver implements to accept raw type matches if the target class has unresolvable type variables. Full generic matches are still preferred; the BeanFactory will only start looking for fallback matches if the first pass led to an empty result.
