Spring Integration also provides a special type router <classname>ErrorMessageExceptionTypeRouter</classname> for routing
Error Messages (a Message with <code>payload</code> of type <classname>Throwable</classname>).
Spring Integration also provides a special type-based router called <classname>ErrorMessageExceptionTypeRouter</classname> for routing
Error Messages (Messages whose <code>payload</code> is a <classname>Throwable</classname> instance).
<classname>ErrorMessageExceptionTypeRouter</classname> is very similar to the <classname>PayloadTypeRouter</classname>.
In fact they are almost identical. The only difference is that while <classname>PayloadTypeRouter</classname> navigates
the instance hierarchy of an payload instance (e.g., <code>payload.getClass().getSuperclass()</code>) to find the most
the instance hierarchy of a payload instance (e.g., <code>payload.getClass().getSuperclass()</code>) to find the most
specific type/channel mappings, the <classname>ErrorMessageExceptionTypeRouter</classname> navigates the hierarchy of
'exception causes' (e.g., <code>payload.getCause()</code>) to find the most specific <classname>Throwable</classname> type/channel mappings.
