DISCLAIMER:
This version of OpenJDK does not aim to be used as a replacement of OpenJDK 8. Due to modifications to java.util classes---java.util.HashMap, java.util.LinkedHashMap, and java.util.concurrent.ConcurrentHashMap---the library is not usable for the execution of Java programs. Instead, it aims to be used as a replacement of the OpenJDK 8 runtime for the sound static analysis of Java programs. The modifications made aim to provide higher precision
and scalability, as described in the PLDI 2020 paper Static Analysis of Java Enterprise Applications: Frameworks and Caches, The Elephants in the Room.
README: This file should be located at the top of the OpenJDK Mercurial root repository. A full OpenJDK repository set (forest) should also include the following 6 nested repositories: "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
The root repository can be obtained with something like: hg clone http://hg.openjdk.java.net/jdk8/jdk8 openjdk8
You can run the get_source.sh script located in the root repository to get the other needed repositories: cd openjdk8 && sh ./get_source.sh
People unfamiliar with Mercurial should read the first few chapters of the Mercurial book: http://hgbook.red-bean.com/read/
See http://openjdk.java.net/ for more information about OpenJDK.
Simple Build Instructions:
-
Get the necessary system software/packages installed on your system, see http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html
-
If you don't have a jdk7u7 or newer jdk, download and install it from http://java.sun.com/javase/downloads/index.jsp Add the /bin directory of this installation to your PATH environment variable.
-
Configure the build: bash ./configure
-
Build the OpenJDK: make all The resulting JDK image should be found in build/*/images/j2sdk-image
where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually is 3.81 or newer. Note that on Solaris, GNU make is called "gmake".
