Code changes required after JDK-8291473

Hi Maurizio,

if I understand it correctly, the "next" branch would be the branch for 
the next JDK waiting to be GA'ed and "main" would hold the currently 
GA'ed JDK (generating binary snapshots)? If yes, wouldn't the same 
problem reappear once development for JDK 21 starts? "next" would be 
pointing to JDK 20 (the next version to be GA'ed) and there would be no 
place for JDK 21.

Best regards,
Filip
