Stuart [in a JBS
comment](https://bugs.openjdk.java.net/browse/JDK-8186958?focusedCommentId=14483078&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14483078)
recommends keeping these factories to the respective classes instead of
`Collections`. In existing code, such factories stay in the respective classes,
including `ConcurrentHashMap.newKeySet(int)`.
Since this is an API change, I suggest you determine where the methods will
stay before filing a CSR request.
