Question

I am trying to use the Spring Framework IoC Container to create an instance of class
ThreadPoolExecutor.CallerRunsPolicy. In Java, I’d do it this way…

import java.util.concurrent.RejectedExecutionHandler;
import java.util.concurrent.ThreadPoolExecutor;
...
RejectedExecutionHandler rejectedExecutionHandler = new ThreadPoolExecutor.CallerRunsPolicy();

But when I try to do the equivalent in Spring, it throws a CannotLoadBeanClassException.

<beans>
   <bean class="java.util.concurrent.ThreadPoolExecutor.CallerRunsPolicy"/>
</beans>

More generally: in a Spring ApplicationContext XML, how can you call a constructor of a static inner class?

Answer 1

I think the reason it is not working is because Spring is not able to understand it as a static inner class.
Probably this can work:

<beans>
   <bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy"/>
</beans>
