ShallowEtagHeaderFilter.setContentLength causes an error when rendering a jsp which performs an include: [SPR-13671]

Neeraj A Khadakkar opened SPR-13671 and commented

This appears to be regression of issue 11717, where attempting to calculate Etag for jsp's which include other tags throws following exception :

Thanks for the report - this seems to have got lost during the refactoring to FastByteArrayOutputStream...
