Oracle is now my friend

Thank you Oracle (Roger and Justin Kestelyn) for getting back to me on my complaint regarding an issue I describe as “not being able to unpack the self extracting binary JDKs from the Oracle download link” below:

Here is the error after downloading this self extracting binary file named “

The download file appears to be corrupted.  Please refer
to the Troubleshooting section of the Installation
Instructions on the download page for more information.
Please do not attempt to install this archive file.

UPDATE:  A UNIX Engineer at my company has solved the problem for me, though I still cannot unpack using his instrux yet in case I need to do this again in the future.  Once I get the exact instrux he applied, I will add them here.

More updates to follow …

Thanks, – Ben


  1. Hi Ben,

    I just ran through this on my Windows machine and FTP'd it over to a Solaris server and was able to install using a .sh file.

    The file I used was, which I downloaded from the URL that you listed.

    It could be that the file was corrupted during the transfer to the server. As this is a .sh file often transfer tools ( like FTP, scp) will transfer these files as text as opposed to binaries. The wrapper is basically text but it does contain binaries which are extracted. As you were able to download and run the tar.Z files, I don't think that your network, proxy or desktop firewall/anti-virus caused the corruption, which we have also seen happen.

    I have pasted the output of my transfer, as a binary, and the extraction below:

    Please try to do the transfer in binary mode. If you still have the problem, send me mail, with an example file, the sever OS and version, as well the steps you took to transfer and extract the file.

    Let me know what you find,

    • Hi Roger, thanks for chiming in on this thread. One of our UNIX Engineers was able to get the specific file I needed unpacked. I have been using binary transfer.
      The files I had been trying are as follows from the download link in the post:
      I will remove the scathing comments from my post now. Personally I have not been able to get this one to unpack. I will comb through your instrux and keep trying just so I can document where I am going wrong.
      I will comment on my progress later.
      Thanks, – Ben

      • Hi Ben,

        Thanks for removing the scathing comments :)
        As you can tell the JavaSE downloads have moved from the site to, and the download process/mechanism has migrated into Oracle's system. The downloads are entered into the system using automated processes, reducing human error and tests are done to ensure that files work as they should. Given the number of downloads we have each day, each hour, or even each minute, they have to work.

        I ran through the example file you gave and was able to download, ftp and extract without any issues. It could be that the download is indeed being corrupted.

        As I had mentioned we do here about individuals having issues with their network infrastructure, local firewalls, anti-virus filters etc, that cause corruptions. One way to see if that is happening is to look at check sums. We do not list them on the Oracle site, though it has been discussed. Below is the checksum I generated and the output of the process I went through. You can generate the checksum on the machine you use to do the download and then again on your sever, assuming you are not downloading directly to the server.

        Sorry that you spent as much time as you did with the download and install. Hopefully your are able to identify the cause of corruption that you are experiencing.

    JDK Downloads Corrupt on Oracle…

    Why are all of the self extracting binaries for JDKs corrupt on Oracle’s download page? Getting the JDK software from Sun was never this difficult. Anybody else run into this problem? I am posting this question on other social media silos as well, so …
