ViewExpiredException is printed in the log even if i set log="false"

See exception.txt for the stacktrace. This is what i have in pages.xml

<exception class="javax.faces.application.ViewExpiredException" log="false">
<redirect view-id="/common/error.xhtml">
<message>#

</message>
</redirect>
</exception>

and the redirect is performed but i still see the exception in the log

Use case to reproduce:

Open a page with a commandButton, restart the application server and when it's started try to submit the form. This will cause a ViewExpiredException.
