JAVA SE 8, JDK-8u151.exe installation doesn't include src.zip file [duplicate]

I installed the JDK8u40, but only find the javafx-src.zip.
Where can I find the source code for JDK? The src.zip?
Below is what I get after installation:
And btw, I didn't see the installation wizard! This is quite strange.
ADD 1
Today I tried several Java installation packages. All are downloaded from Oracle official site.
jdk-6u45-windows-i586.exe
jdk-7u75-windows-i586.exe
jdk-8u20-windows-i586.exe
jdk-8u25-windows-i586.exe
jdk-8u31-windows-i586.exe
jdk-8u40-windows-i586.exe
Both 6u45 and 7u75 installed well on my box. I can see the install wizard. And the src.zip is installed.
But 8u25 ~ 8u40 all installed silently. And no src.zip file is installed because I have no chance to select it in the wizard.
I am not sure if this is my fault or someone at Oracle made a mistake.
As #SubOptimal commented, the /s option indicates a silent install. I am wondering if there's an option to force the GUI install wizard to open.
I am using Windows 7 Enterprise x64 Build 7601 SP1

Make sure the Source code is not disabled when downloading.
Then as you can see on the picture, selecting "Source Code" will tell you exactly where it is located.
Notice that I've downloaded the 32 bits version to make sure to reproduce the same use case as you.
Edit
As per your new edits and comments, it seems what you want to know now is why you don't see the installation wizards. I'm pretty sure this is due to old-set registry key.
Run the following command
reg query hklm\software\microsoft\windows\currentversion\installer\UserData\S-1-5-18\Products /f "java" /s | find "HKEY_LOCAL_MACHINE"
Now, navigate to each of the returned path browsing with regedit and delete their entire parent (the big hexa number).
Re-try the installation and I'm pretty sure you will see the wizard.
As for the sources, Oracle documentation specify how to download them in silent mode.
jdk.exe /s ADDLOCAL="SourceFeature"

This is the way I got the src folder from jdk-8u172-windows-x64.exe file without installing.
Step1: Download jdk-8u172-windows-x64.exe file (Java SE Development Kit 8u172) from oracle site
Step2: Extract it and navigate to the path:
\jdk-8u172-windows-x64.rsrc\1033\JAVA_CAB9
Step3: Right click on file named "110" and extract it.
You will get the src.zip file.
It took me little while to figure this out. I hope it will help others.
Enjoy debugging Good Code!

I don't know why/where the src.zip is, but as an alternative, if all you want is the source and somehow the proposed method doesn't work for you, you could always pull directly from the JDK8u40 source tree.
You will need Mercurial instead of Git. This link talks about the hg clone command
Quoting from the OpenJDK Java.net site
The corresponding master forest jdk8u can be cloned using this command: hg clone http://hg.openjdk.java.net/jdk8u/jdk8u;cd jdk8u;sh get_source.sh .
In addition, the source code for the last release, 8u40, is available by cloning the 8u40 master forest : http://hg.openjdk.java.net/jdk8u/jdk8u40. The final build of that release was tagged as jdk8u40-b25.
There are differences between OpenJDK and Oracle's, though subtle

download JDK 8 from following link
http://www.oracle.com/technetwork/java/javase/jdk-8-readme-2095712.html
src.zip comes in-built with it

if you JDK installer silently skips installing the source. just open the control panel > programs an features and find Java. Right click on it and select change and then select the
source (option) ;)

Download the JDK
Run the Installer, but stop right away
Extract src.zip from C:\Users\<your_username>\AppData\LocalLow\Oracle\ss180121.cab
You can extract .zip from .cab with tool like 7Zip

Eclipse IDE on Mac?

I'm trying to get Eclipse 4.5.2 running on Macs with OS X 10.10.5 and Oracle Java 8u73 I got to the point where trying to start Eclipse results in
The JVM shared library "$JAVA_HOME/bin../jre/lib/server/libjvm.dylib" does not contain the JNI_CreateJavaVM symbol.
Googling this returns a whole bunch of suggestions, none of which work. Some say you absolutely MUST have the JDK (I'm using the JRE). Others emphatically say the JRE is all you need. Some suggest editing an Info.plist or another, with people responding "Yeah that worked!" right along with "That didn't work"
How do I get past this message?

You need the JDK because, well, to be honest Apple hates Java and has done a thorough job of screwing up what used to be the best OS for Java development.
The "you need legacy Java" message was from OS X, not Eclipse. The advice to download and install it is bad advice, but sadly nothing that Eclipse can remedy. Installing "legacy Java" just reverts your system to a VERY outdated JRE and renders much Java-based software, including Eclipse, broken.
Eclipse requires Java 7 or above (this year's release of Eclipse packages in June will require Java 8 ), so the best thing is to download JDK 1.8 (not just the JRE), install that, then point your eclipse.ini file to it's exact location per the instructions at the eclipse.ini wiki page.
Oracle JDK download links change often, so it's best to Google for "JDK 8 download" and you'll find it. Here's the page as it stands at the time I'm writing this.

JDK documentation in IntelliJ IDEA on Mac OS X

I'd like to know how to setup IntelliJ to point to the JDK documentation so the documentation popups that display during code completion will show me what the function I'm looking at is going to do. For some reason IntelliJ isn't able to find the JavaDocs by default.
I'm also not 100% sure that the documentation is installed with the JDK that's installed with the OS. I don't see them in /System/Library/Frameworks/JavaVM.framework/ but I may be looking in the wrong place. If it's not included, I'd also like to know what needs to be downloaded and where it needs to be installed to get the JavaDocs for the JDK to show up in IntelliJ.

I had to combine the responses I got to this point and add a few extra details so I'm answering my own question.
Search for "Java developer" from Downloads for Apple Developers
Download and install "Java for Mac OS X 10.6 Update 9 Developer Package" (or later).
In IntelliJ, open File -> Project Structure.
Click on "SDKs" under "Platform Settings".
Add the following paths under the "Documentation Paths" tab (the paths may be different based on which JDK you're using):
/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk/Contents/Home/docs.jar!/docs/api
/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk/Contents/Home/appledocs.jar!/appledoc/api
Add the following path under the Sourcepath tab:
/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk/Contents/Home/src.jar!/src
Thanks, #Yishai for the download location and #Gareth Davis for the location of the documentation after installing.
Update for 10.7/10.8 [Mountain] Lion:
Steps are the same except for these changes:
In step 2, download "Java for OS X 2012-005 Developer Package" (or later).
Use these paths instead in step 5.
/Library/Java/JavaVirtualMachines/1.6.0_35-b10-428.jdk/Contents/Home/docs.jar!/docs/api
/Library/Java/JavaVirtualMachines/1.6.0_35-b10-428.jdk/Contents/Home/appledocs.jar!/appledoc/api
Use these paths instead in step 7.
/Library/Java/JavaVirtualMachines/1.6.0_35-b10-428.jdk/Contents/Home/src.jar!/src

Quick (and dirty?) solution: Point IntelliJ to http://download.oracle.com/javase/6/docs/api/

have you installed the Apple Java Developer package?
It provides src.jar and docs.jar in /Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk/Contents/Home
Note this is since update 3. If these are present Intellij will just find them, or at least mine did.
details are in the Java update release notes

This should tell you what you need to know: Get local copies of Mac OS X Java source code and Javadoc – Concord Consortium wiki.
That page recommends going to https://connect.apple.com and downloading and installing “Java for Mac OS X 10.5 Update 2 Developer Documentation (Disk Image)” or the equivalent newer release. It describes a few ways to view the documentation, based on the Java jar file being located at a path like this:
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/src.jar

Source code for the Java library classes

Where can I find the source code for the Java library classes? I mean classes in rt.jar.
Platform: Windows.

For old versions of Java with separate JRE and JDK downloads, download the JDK. The sources for the public classes are in src.zip.

Here's the browsable source code for OpenJDK 7.
Update: As of June 2018 grepcode seems to be down. Here you can find an alternative.
Update^2: As of October 2020, the two previous links do not work. View it at OpenJDK and vote up the answer by Nosrep, which I got it from.

Sources are in src.zip located in the installation folder:
On Windows, the JDK includes src.zip by default if I remember well.
On a Linux distro, you may have to install the sun-java6-source package.
On Mac, you'll have to download the Developer Documentation. Have a look at this answer.

If you only need to have a look at the source/implemenation, i would suggest using
Docjar
Edit
GrepCode is even better
GrepCode

You can directly browse the code online here for Java : https://zgrepcode.com/java/openjdk/10.0.2/
It is a great tool also for browsing most of the open source projects as it gives you internal linking to classes.

As almost all the suggestions seem to be either grepcode or zgrepcode which are both down, I found one from OpenJDK here: http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/tip/src/share/classes/
Edit: a more complete version of all OpenJDK projects and JDK 6-15 can be found here: https://hg.openjdk.java.net/

As mention above, most of the source files can be found by downloading the SDK.
However for some classes you can find the source code (javax.ssl etc') for I suggest adding the jad eclipse plugin that will decompile any class without using external site such as Docjar.
Jad eclipse info:
http://jadclipse.sourceforge.net/wiki/index.php/Main_Page

There is also grepcode.com (not sure how old this site is, perhaps this answer is an update for new solutions now), sample query:

Intellij IDEA setup on OS X

What's the accepted procedure and paths to configure jdk and global library source code for Intellij IDEA on OS X?

As of the latest releases:
Java for Mac OS X 10.6 Update 3
Java for Mac OS X 10.5 Update 8
Apple has moved things around a bit.
To quote the Apple Java guy on the java-dev mailing list:
System JVMs live under /System/Library/...
These JVMs are only provided by Apple, and there is only 1 major
platform version at a time.
The one version is always upgraded, and only by Apple Software Updates.
It should always be GM version, that developers can revert back to, despite
any developer previews or 3rd party
JVMs they have installed.
Like everything else in /System, it's owned by root r-x, so don't mess
with it!
Developer JVMs live under /Library/Java/JavaVirtualMachines
Apple Java Developer Previews install under /Library.
The Developer .jdk bundles contain everything a developer could need
(src.jar, docs.jar, etc), but are too
big to ship to the tens of millions of
Mac customers.
3rd party JVMs should install here.
Developers working on the JVM itself can use
~/Library/Java/JavaVirtualMachines
It's handy to symlink to your current build product from this
directory, and not impact other users
Java IDEs should probably bias to using /Library or ~/Library detected
JVMs, but should be able to fallback
to using /System/Library JVMs if
that's the only one installed (but
don't expect src or JavaDoc).
This allows Java developers the
maximum flexibility to install
multiple version of the JVM to regress
bugs and even develop a JVM on the Mac
themselves. It also ensures that all
Mac customers have one safe, slim,
secure version of the JVM, and that we
don't endlessly eat their disk space
every time we Software Update them a
JVM.
So, instead of pointing Intellij at /System/Library/Frameworks/JavaVM.framework, you should point to a JDK in either /Library/Java/JavaVirtualMachines or /System/Library/Java/JavaVirtualMachines

In the 'Project Settings' window, go to 'JDKs' section that you see under'Platform Settings'. Click the little plus sign and choose 'JSDK'. A file chooser should open in the /System/Library/Frameworks/JavaVM.framework/Versions directory. If not then just navigate to it. There you can choose the version you would like to add.

IntelliJ should detect your installed JDK's, as they are in a standard location that Apple provides. If you want source code for the JDK, you can download that from Apple as well. Sign up for a free ADC account and then you can get access.
For global libraries, I've been enjoying the Maven integration in the recent release. It alleviates the need to setup global libraries by pulling things from the Maven repository. It will download source and javadoc jars as well.

the JDK that comes with osx doens't include the source. you need to log into the apple developer site with your apple account to find the developer version of the SDK which includes src.jar.
http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wo/5.1.17.2.1.3.3.1.0.1.1.0.3.1.3.3.1

The post from intellij support page explains how to configure the JDK which Intellij uses to run itself.
