Looking for a sponsor for JDK-8138732

[Philippe Marschall]

Hello

I am looking for a sponsor for JDK-8138732 [1]. The ready to integrate
PR is here [2].

Changes between the current code and the reviewed code:

- I removed the jdk.internal export to jdk.jfr, that was a review comment.
- I had to rebase and resolve a merge conflict with JDK-8243066.

  [1] https://bugs.openjdk.java.net/browse/JDK-8138732
  [2] https://github.com/openjdk/jdk/pull/45

Cheers
Philippe
