   I share reservations of @mbien and @matthiasblaesing It's an interesting exercise, but could never be the default option, adds complexity to the build, and isn't really the best test of nb-javac IMO.  Tests using modern language features and comparing output with the un-backported javac would seem more useful?  Still, I'm -0 as long as it doesn't break things!
   
   > nb-javac is currently also not in this repository (or even an apache project unless I miss something obvious), so I am not sure what you mean by "eat your own dog food".
   
   Well, nb-javac is not an Apache NetBeans project, and _cannot_ be developed as an Apache NetBeans project*.  Unless something significant changes in ASF rules, nb-javac is never going to be our "own dog food".  Compiling NetBeans might be considered to be.
   
   Whichever, the responsibility for development and the bulk of testing nb-javac needs to remain external.  If this change helps with testing _upstream_, it could go in.  We could even consider running that build test in CI here, but I'd probably limit that to nb-javac update PRs.  We don't have unlimited capacity.
   
   * one option to investigate, and discussed previously, might be running the backport javac build inside the NetBeans build, assuming no GPL+CPE sources required on our side.  That would still need some checking with legal.
   
   > We should rather concentrate on upgrading everything to JDK 11 which actually solves problems and has likely community consensus as I gather from the last thread about it. @neilcsmith-net drafted a proposal for this.
   
   +1 to that, but I don't think there's any overlap in the two things.  nb-javac cannot help with our requirements to update minimum JDK, and upgrading the base to JDK 11 then 17 won't remove our reliance on nb-javac for Java editing.
