I think it would be useful to have an answer to this CSR question:
https://bugs.openjdk.org/browse/JDK-8350492?focusedId=14755916&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14755916

I suspect best would be to have some tests for the Filer methods.

Please note you'll have to mark the CSR Finalized before it is considered again. Thanks!
