Hi,

In CardTableBarrierSetAssembler, we sometimes need fencing due to the card table being scanned concurrently when using CMS with pre- cleaning. Rather than explicitly checking for those CMS flags in the generic CardTableBarrierSetAssembler class, it is preferrable to check the CardTable scannedconcurrently() property which already precisely reflects that. Bug: https://bugs.openjdk.java.net/browse/JDK-8202082 Webrev: http://cr.openjdk.java.net/~eosterlund/8202082/webrev.00/

looks good.
