I've submitted a JEP for (1) enabling the use of C++14 Language Features when building the JDK, (2) define a process for deciding and documenting which new features can be used or are forbidden in HotSpot code, (3) provide an initial list of permitted and forbidden new features. https://bugs.openjdk.java.net/browse/JDK-8208089 While there has been some discussion of this JEP here, so far only Mikael has officially reviewed or endorsed it.

I added myself as a Reviewer.

Regarding the timing of this JEP, integration in time for JDK 12 seems unlikely.

This doesn't strike me as a JEP that actually integrates anything. It wants to establish a process by which future C++ features are accepted for use with hotspot. That's just documentation on the OpenJDK wiki as far as I can see. The actual set of features and any "vote" on them can happen any time after the JEP is approved. Any actual use of those features can follow any time after that.

I think it is important that all the port owners buy into this.

Thanks, David
