在Mac OSX 10.10系統上編譯了下OpenJDK9，以下僅是個人安裝記錄，供參考。
編譯時間：2015-06-13
系統版本：Mac OS X Yosemite 10.10.4
編譯OpenJDK版本：JDK 9
相關軟件版本：
參考資料：
OpenJDK Home Page
OpenJDK官方編譯步驟（下載完源碼裡面就有README-builds文件）
JDK BUG System（編譯遇到問題可以上面搜索）
OpenJDK官網操作系統等要求
編譯前期准備：
•大致了解官網系統要求：
https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms
•源碼下載工具安裝（此處采用Mercurial工具[OpenJDK的版本管控工具]從官網下載）：
安裝參考資料：
http://openjdk.java.net/guide/repositories.html
https://mercurial.selenic.com/wiki/Download#Mac_OS_X
本機安裝腳本：
安裝：
$ brew install mercurial
若link失敗，則：
$ sudo brew link mercurial
驗證版本不低於2.6.3：hg version
安裝後版本3.0.2，改為官網下載安裝3.4.1了
•安裝ccache提高編譯速度
$ brew search ccache
$ brew install ccache
•安裝freetype（編譯時需要）：
brew install freetype
安裝失敗，提示依賴的libpng無法下載。手工安裝：
下載libpng最新版1.6.17(http://sourceforge.net/projects/libpng/files/)並解壓：
$ pwd
$ cd ./libpng-1.6.17
$ ./configure --prefix=/usr/local/libpng-1.6.17
$ make
$ make install
$ cd /usr/local/
$ ln -s libpng-1.6.17 /usr/local/libpng
$ brew install freetype
•獲取JDK源碼：
$ mkdir OpenJDK9;cd OpenJDK9
$ hg clone
$ cd dev
$ chmod u+x get_source.sh
$ ./get_source.sh
編譯配置：
$ bash ./configure --help=short
$ bash ./configure --enable-debug --with-target-bits=64
...

解決辦法如下或者替換XCode版本為6.3.2或者5.幾的：
//OpenJDK9/jdk9/jdk/src/java.desktop/macosx/native/libosxapp/NSApplicationAWT.m
//387行改成：
if (NSApp != nil) {
//[NSApp setDelegate: applicationDelegate];
[(NSApplication*)NSApp setDelegate: applicationDelegate];
if (applicationDelegate && qad) {
[qad processQueuedEventsWithTargetDelegate: applicationDelegate];
qad = nil;
}
}
重新編譯：
$ make clean
$ make
...

解決辦法：

//855行改成如下的（注釋掉IF條件）：
else /** if (rasterP->sppsm.offsets != NULL) **/ {
