Hi,
When creating a ciInstanceKlass handle, G1 might need a SATB barrier to keep "peeked" weak klass pointers alive during marking. This should now be done with the Access API instead of manual calls to the G1 SATB barrier. Bug: https://bugs.openjdk.java.net/browse/JDK-8191567 Webrev: http://cr.openjdk.java.net/~eosterlund/8191567/webrev.00/
looks good.
Thanks for providing such nice usage examples for the new Access klass separately from the huge Access change :)
Thanks, Thomas
