Downloading source
I'm not able to reproduce the problem. Are you still having trouble downloading the source file? I'm able to download it fine on my computer.
BTW, I should note that these files are very outdated-- they are from work on Edition 4, which has been superseded by work on Edition 5 and Harmony.
I've updated the ecmascript.org web site so it reflects some of the more recent work on Edition 5 and Harmony, and noted that the reference implementation work is no longer current. My apologies for not updating the web site sooner.

Based upon your email, I tried to download the source again. The very first time I had tried to download the source, about a week ago, I could get 77% of the file and then the downloading hung and subsequent attempts would not download anything. Well, same thing just happened. I got 77% and the downloading then just stopped. Now, if I try I can not get any of the source to come down. (My ISP does not limit the of downloads).
My real issue is more meta. I've got a javascript constraint engine which seems to work with SpiderMonkey 1.8. What I'd like to do is create a version of the constraint engine code that uses some of the new javascript features such as "class". Thats why I was interested in getting the es4 source so I could compile it on my 64 box and test my port. Are there any javascript implementations out there, even if they are pre-release, that I could get that have the new features?
Thanks.

Unfortunately this is really not the program you want. The RI you're trying to download was an experimental interpreter for spec purposes, following a language design that is no longer on the table; it would not have performed adequately, even if it was implementing a language likely to be approved.
As it stands, the language it interprets is not the language approved as ES5 (not even close) and it's not clear that the committee is likely to follow along much of the work that was done on that RI.
In other words, it's more of a historical artifact at this point than a representative of current committee effort or consensus. It's not worth using in the way you describe.
Sorry,

I don't see anything in the server logs, so I'm not sure what to tell you. You could try to download it from another computer. I'd be willing to put the file up on another temporary server for you, but I suspect this isn't actually going to help you, because...

ES4 has been superseded by the work on ES5 and ES6 ("Harmony"). Classes are still being discussed as part of the design for Harmony, but they will most likely be significantly different from the classes of the proposed ES4. I wouldn't recommend starting a new project based on the proposed features of ES4.
I was visiting www.ecmascript.org and decided that I'd like to run the early access RefImpl on my 64bit linux box. So, I tried to download the source from www.ecmascript.org/download.php es4-pre-release.M2.source.tar.gz
No, luck. I get to the license page, click agree and the continue button but nothing happens and the site times out. I can download the pre-build files just not the source file.
Thanks
