Jan Lahoda commented on NETBEANS-242:
-------------------------------------
FWIW, my take is that bugs that are NetBeans bugs (like this one) should be
fixed in the same mode as any other NetBeans bug.
For javac/JDK problems, I'd say it is a combination of severity of the problem
and the difficulty of the workaround. Simple workarounds inside the modules
that integrate javac into the IDE are surely less troublesome than wide-spread
workarounds that would require significant changes in the features. I think we
should (try to) avoid the situation of having the code littered with too many
workarounds. But there were multiple workarounds done already, to avoid too
much trouble when using the vanilla javac. (Although I am e.g. less inclined to
workaround problems that I know are fixed in the future JDK 10).
