RFR: JDK-8072913: [REDO] GCCause should distinguish jcmd GC.run from System.gc()

[Yasumasa Suenaga]

Hi all,

I've committed JDK-8068589 to add new GCCause - Diagnostic Command.
However, it has been backouted because test is failed [1] and it is not considered
about concurrent GC: -XX:+ExplicitGCInvokesConcurrent [2].

I've created patch for this enhancement.
Could you review it?

I'm jdk9 committer, but I'm not employee at Oracle.
So I need a Sponsor.


Thanks,

Yasumasa
