> Key: WW-4433
> URL: https://issues.apache.org/jira/browse/WW-4433
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Documentation, Plugin - Convention
> Affects Versions: 2.3.20
> Reporter: Joseph Wolschon
> Assignee: Lukasz Lenart
> Priority: Minor
> Fix For: 2.3.21
>
>
> Struts 2.3.20 appears to have caused a regression that prevents exceptions thrown from convention-plugin actions from reaching ExceptionMappingInterceptor. This breaks exception handling when using the convention-plugin.
> To Reproduce:
> * Generate a project struts2-archetype-convention archetype using 2.3.20
> * Throw exception in the action. With 2.3.20, a blank page is shown.
> * Change to 2.3.16.3 and you will get the standard struts2 error page.
> The breaking change appears to have been made in WW-4331. This causes error interceptor code to break (showing a blank page when exceptions are thrown) as DefaultActionInvocation does not catch an exception from the default UnknownHandler implementation execution, which would previously re-throw the original exception back up for the interceptors to catch.
> Workaround:
> We've created our own UnknownHandler implementation that just throws a new NoSuchMethodException, allowing DefaultActionInvocation to re-throw the original exception so that our error interceptor can again catch it.
