Frgaal, that'd be fantastic! As far as I know the latest version supports all JDK16 features including records. Fellow developers could code with the newest language features, while still target JDK8 APIs and bytecode version. Anyway, let's go step by step. Using JDK-11 to compile NetBeans seems to have overall support and seems to be moving in the right direction. -jt PS: Ernie, if you decide to enable Frgaal compilation (see PR-2369 for inspiration), you'll get my support. > On 9/30/2021 11:27 PM, Jaroslav Tulach wrote: > > JDK17 is out and Geertjan told me the old request is going to appear > > again. > > Let me thus review an old thread from November/February... > > > > ---------- Forwarded message --------- > > From: Jaroslav Tulach <[email protected]> > > Date: Feb 9 2021 > > > > Hi. > > I knew the time for a discussion like this is going to come when I wrote > > my > > "Compile with JDK-11 javac --release flag" in November.
