JEP 475 is now open for porting

[Amit Kumar]

Hi Roberto,

I just want to understand how this is gonna move forward. The build is broken with these changes.

Are you gonna wait until We all finish the Ports ?
Are we gonna integrate our changes before this change merges so that we don’t face a build break ?
Is there a flag to turn it off completely? I tried to look into src/hotspot/share/gc/g1/g1_globals.hpp and surprisingly it didn’t work.

Thanks,
Amit Kumar
