Hi, [TL;DR: I'm offering patches to compile JDK 9 on FreeBSD, but it's not clear where to put them, or how.] I'm working at Oracle on the OpenJDK build team and is responsible for large parts of the build system of OpenJDK. Lately, I've been playing around with FreeBSD (and other BSDs) in my free time, and I've written a patch that will add build system support for FreeBSD, OpenBSD and NetBSD in JDK 9 (tracked in https://bugs.openjdk.java.net/browse/JDK-8147795). I started writing this when I realized that the jdk9 branch in the OpenJDK bsd-port repository did not contain any BSD-specific changes at all, and the old JDK 8 changes will not readily be portable, due to major changes in the build system between JDK 8 and JDK 9. I thought it would be a no-brainer to integrate these changes into the JDK 9 mainline, so they would be in place for whenever you guys would start to attack porting the code base. However, some of my collegues thought otherwise. The end result, I think, is that they wanted to see someone (not necessarily a company, the FreeBSD organisation for instance seemed to be okay), to step forward and say "we take responsibility for the BSD port", and give some kind of commitment to actually use these build changes in producing a viable port. You can read the mail conversation here: http://mail.openjdk.java.net/pipermail/build-dev/2016-January/016421.html An alternative to pushing this code into the JDK 9 mainline is of course to push it to the bsd-port/jdk9 repo (given that the owners of that repo approves), but that seems like a less favourable solution. Having the code in the mainline does not mean that it gets tested automatically, but it means that it will be part of e.g. refactoring, that would otherwise break a downstream patchset. I cc:ed this conversation to the bsd-port-dev@openjdk.java.net mailing list, but never got any kind of official response there. Since this list seems more active, I'm trying here instead. :) So, I'm offering two patches here, one that applies to the build system, is nice and clean, and possible to integrate into JDK 9 mainline, if my collegues are convinced that someone is backing up the BSD port. And there's a second patch, which fixes broken C/C++/Java code and results in a product that can at least run "javac HelloWorld", but this is not yet clean enough for integration anywere, at least not the JDK 9 mainline. (I don't know enough of the BSD internals to fix all problems, so there's some "#if 0" code here and there.) /Magnus
