Hi all,

I am interested in doing the backport work for JDK-8205516: JFR tool
[1] to openjdk 11u. A CSR was filed for the original bug so I believe
I will need to file a CSR for the backport bug [2] as well. However, I
am not an author or a committer; is this something someone can do in
my stead?

Also: why should the JFR tool be backported to 11?

JFR is now in openjdk 11+. In order to extract information from flight
recordings, one would need to write a parser, maybe using existing
java libraries like jmc-core, download a separate tool (if any exist),
or use JMC, a full fledged GUI application. A CLI tool that is part of
the JDK is a very good alternative and I think it makes sense for the
JFR tool to be available in JDKs that support flight recordings,
including 11.
