No, not at all! I just confused the "what JDK the IDE is running on" vs. "what JDK the project is compiled with" when interpreting your proposed restriction.
Ideally, a warning should be shown to a user if they try to use a JDK 8 project while running the IDE on a JDK that does not support this. It's a little unintuitive to have to juggle two JDKs here, but that seems a reasonable price to pay if the user really wants to work with a project that must compile with an old JDK. -- Eirik -----Original Message----- From: Geertjan Wielenga <geert...@apache.org> Sent: Tuesday, April 28, 2020 12:53 PM To: dev@netbeans.apache.org Subject: Re: nb-javac and the upcoming 12.0 Hopefully that’s not sarcasm. :-) Gj On Tue, 28 Apr 2020 at 18:43, Eirik Bakke <eba...@ultorg.com> wrote: > Oh, now I get it.
