There was a related issue at https://bugs.openjdk.java.net/browse/JDK-8170591 about going back to javah instead of javac -h but that doesn't talk about why the headers for Character and IDN are needed.
I'm building without those headers (takes almost 1 hour though to build webkit on linux) so I'll find out if they are needed on linux. - Johan On Thu, Nov 30, 2017 at 11:42 AM Johan Vos <johan....@gluonhq.com> wrote: > I filed a bug (https://bugs.openjdk.java.net/browse/JDK-8192806) and I am > looking into it. > > It seems a bit weird to me that the java.lang.Character and java.net.IDN > header files are needed.
