How to download OpenJDK 8 source code from java.net

I need to have access to the source code of some classes from the sun.* packages of Java 8 for my project. I found it on https://download.java.net/openjdk/jdk8/, but the link is for OpenJDK 8u0. I also found a link to 8u40 (http://download.java.net/openjdk/jdk8u40/ri/openjdk-8u40-src-b25-10_feb_2015.zip) from Googling, but I can't find any page on java.net that references it. How can I find a link to the latest stable OpenJDK 8 version (8u192) source code from java.net or at least something more recent than 8u40?

Please note the following:

  1. I specifically want the source code of OpenJDK 8 because the Oracle JDK source code doesn't contain the sun.* packages that I need.
  2. I'm aware that public updates for Java 8 stop after 8u202 that will be released this month. As I only need the source code for reference, it doesn't matter in my case.
  3. I would prefer OpenJDK directly from Oracle (from java.net) instead of third-party vendors like Adopt or Azul.
  4. This question is not "Questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource" because I don't ask for any recommendations or opinions. I'm asking for source code for a very specific thing that should be publicly available as OpenJDK is an open source project.

First of all. Oracle JDK is in essence OpenJDK because Oracle handed over (nearly) the whole stuff over to OpenJDK. Oracle JDK can be seen as one VM based on OpenJDK as there are others. What is stopping this month is the free availability of OracleJDK-updates, etc. but that has no effect on the other VMs out there.

The source can be accessed (including newer versions after Oracle stops their free support) at the Mercurial Repositories at http://hg.openjdk.java.net. The sources you're looking for should be available at http://hg.openjdk.java.net/jdk/jdk/tags

Edit: Because you asked in a later comment in your question: You can download the source of a given project by clicking onto one of the links on the left side of the page showing the names of archive-files (bz2, zip tar) at the start-page of a given tag.

Edit2: Because you asked for Java 1.8.0_192 (I assume b26), you can use http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/archive/996dd3ce1ec5.zip. Here are the steps to get to it: From the main page go to the Project jdk8u (http://hg.openjdk.java.net/jdk8u). Select jdk8u-dev->JDK (http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/). Click on "Tags" (http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/tags), select "jdk8u192-b26 " (http://hg.openjdk.java.net/jdk8u/jdk8u-dev/jdk/rev/996dd3ce1ec5) and click on one of the archive-formats on the left, e.g. ZIP (see above).
