I tend to trust more official sites:
That have been building it for awhile in comparison to a almost empty google code project page.

Also most people shouldn't install this as Oracle / Apple will provide a stable build (updating the Safari Plugin for one which this will not provide). Apple has a beta build of update 29 that they are working on of JRE 6. So it's going to be awhile till we're "first class" supported. So please install with care and understand that you probably will not even be using this if you install it.

I agree. The official site with pre-compiled binaries and all the instructions is here:


MU should not allow unofficial listings except in rare circumstances where only source code is available, and posting a pre-compiled binary is providing a service that can't be found elsewhere. Even then, listings like this should be clearly marked as UNOFFICIAL so that those who take system security and integrity seriously, can avoid them.


Looks like you did not pay attention that http://code.google.com/p/openjdk-osx-build/ is not an official site too.

Both sites are offering compiled version of OpenJDK and both are unofficial...

For now there are no other option to get compiled version of OpenJDK


it might come as a surprise to you guys but OpenJDk and java both belong to Oracle. OpenJDK official site is http://openjdk.java.net/

notice the java.net in the url. It belongs to Oracle. This binary link IS OFFICIAL


OK for Java.net, this site is now Oracle (used to be Sun) but there is no binary for Mac out there for now.
Just a rought How To build and access to openjdk sources


Click on "Visit Developer Site" link above and you will get your binary.


And so what so far. Novelty is not an issue as long as it works, what is the case.
In addition; http://jdk7.java.net/macportpreview/ is offering Official binaries... So following your argument I should donwload only from them.
OpenJDK is open as written in its name and for that reason there could be more than one people providing binaries of it.
