> My team uses a custom subclass of ServletRedirectResult, e.g. "org.tdar.struts.ServletRedirectResult". After updating to 2.3.8 our messages no longer survive a redirect.  I believe the problem lies with this section of [MessageStorePreResultListener|https://git-wip-us.apache.org/repos/asf?p=struts.git;a=blob;f=core/src/main/java/org/apache/struts2/interceptor/MessageStorePreResultListener.java;h=60fcffe2116f16503ba6540ff9f69b25dac173f1;hb=8852618]: 
> {code}
> if (resultConfig != null) {
>     isRedirect = ServletRedirectResult.class.getName().equals(resultConfig.getClassName())
>             || ServletActionRedirectResult.class.getName().equals(resultConfig.getClassName());
> }
> {code}
> Per the discussion in WW-4605,  the following change could likely resolve the issue:
> {code}
> if (resultConfig != null) {
>     isRedirect = ServletRedirectResult.class.isAssignableFrom(Class.forName(resultConfig.getClassName()));
> }
> {code}
