property permissionEvaluator of DefaultMethodSecurityExpressionHandler is always DenyAllPermissionEvaluator in child application context

spring-security version 4.1.3.RELEASE

I have root application context and I created a new child context while initializing root context.
Root context has configuration bean GlobalMethodSecurityConfiguration:

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration
{
... 
    @Bean
    public MutableAclService aclService()
...
    }

    @Bean
    public PermissionEvaluator permissionEvaluator(AclService aclService)
    {
        return new AclPermissionEvaluator(aclService);
    }
...
}

while root context initializing created a new child context

migrationContext = new AnnotationConfigApplicationContext();

            migrationContext.setParent(applicationContext);

in child context created beans which call some protected methods with PreAuthorize("hasPermission(...)") annotation
but I always get AccessDeniedException
because root context is in initializing method GlobalMethodSecurityConfiguration.afterSingletonsInstantiated is not called yet
and expression evaluator uses default permission evaluator DenyAllPermissionEvaluator but expected to be used AclPermissionEvaluator.

Before changes in afterSingletonsInstantiated method GlobalMethodSecurityConfiguration configures defaultMethodExpressionHandler correct autowired permission evaluator (AclPermissionEvaluator).

How to correct configure GlobalMethodSecurityConfiguration before child context will be create?

Trace GlobalMethodSecurityConfiguration.afterSingletonsInstantiated and the DefaultMethodSecurityExpressionHandler setup, then compare that lifecycle with creation of the child AnnotationConfigApplicationContext. Verify when the permission evaluator is selected and confirm that the child-context calls using PreAuthorize("hasPermission(...)") use the configured AclPermissionEvaluator rather than DenyAllPermissionEvaluator.
