Refreshing annotated Groovy controllers cause ClassCastException [SPR-10253]

[spring-projects-issues]

arnolf opened SPR-10253 and commented

To use Groovy controllers, proxy-target-class attribute has to be set to true (#10935).
To turn on the refreshable beans feature, refresh-check-delay has to be set.

<lang:groovy refresh-check-delay="500" proxy-target-class="true" script-source="classpath:TestController.groovy"/>

When we use both, refreshing modified Groovy controller throws ClassCastException :

java.lang.ClassCastException: TestController cannot be cast to TestController
