This means: Hold stream till end-of-processing. This allows: reset
response completely, and output clean error page, without parts of XML
previously processed.

Then the pipeline which called this internal one will never know that
exception happened: it will get either result, or partial result and
error (IIRC).

Try also increasing buffer of the serializer, then environment will be
able to reset the partial result and output clean error page. From the
Environment:
---------
/**
* Reset the response if possible. This allows error handlers to
have
* a higher chance to produce clean output if the pipeline that
raised
* the error has already output some data.
*
* @return true if the response was successfully reset
*/
boolean tryResetResponse();
