Hi,

in the thread "JEP 248: Make G1 the Default Garbage Collector" [1] there is an email from Jeremy Manson, who mentions the enhancements made by Google to improve CMS.
Especially the parallelizing of full compaction is a great improvement and we at SAP see the strong demand of it.


@Jeremy: Are these changes published somewhere? May we have insight into the diffs you've made? We could collaborate in order to try to bring your changes into OpenJDK.



Kind regards and thank you in advance,

Ivan
