Can Java 9 run on a 32-bit OS?

Seems there are no 32-bit download packages on Oracle's available download list.

UPDATE

Can download here:

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/9+181/jdk-9_windows-x86_bin.exe

Although the 32-bit binaries for JDK9 seem to be missing from Oracle's lousy, unencrypted download page, if (after clicking "Accept License Agreement") you copy the URL of the 64-bit binaries and change x64 to x86, it will give you the 32-bit binaries.

---

Update: And now it's gone. Bizarre! What is Oracle playing at? They went to the effort to fix x86-specific bugs for Java 9, they explicitly said 32-bit Windows and Linux were supported, they list installation instructions for 32-bit systems, they made 32-bit builds fully available throughout the pre-release period for testing purposes, and nothing in their JDK 9 migration guide indicates that 32-bit platforms have been dropped (quite the opposite in fact: it says the -client VM command line option has been dropped so the faster -server VM is now the default for 32-bit).

So why are they suddenly hiding the release binaries?

I happened to have downloaded the Windows JDK (including JRE) and the Linux JRE for x86. I don't have the Linux JDK. There's an Oracle digital signature in the properties of the Windows exe so you can see that it's genuine. I do hope Oracle get their act together.

Update 2: Apparently Oracle has decided to eliminate support for x86 Java forever. They somehow finished, compiled, digitally signed, and published the Java 9 binaries by accident. The binaries still work, but presumably will not receive updates.

---

Update 3: Apparently Oracle has become so hateful and hostile towards Java developers that they have compelled Google to block the above downloads with a DMCA request. Nothing I can do. Sorry. If you have Java 9, you have it, and it will still work. If you don't have Java 9, well, you'll have to get creative.

> Yes, you can build your own 32-bit JDK 9 binaries.

I found a Win32 build here: https://github.com/ojdkbuild/ojdkbuild

This is a OpenJDK provided by RedHat (without support), no idea if they will provide those builds in future.

Oracle has dropped Windows 32-bit Client VM

However: The statement there "In JDK 9, the Windows 32–bit client VM is not available. Only a server VM is offered." is not even accurate, there is not even 32-bit server VM (as of Sep 27, 2017).

Update: Not just Windows, but no 32-bit for any platform is available.

Try the below link for openJDK, offers X86 (32bit) and X64 (64bit) for most java versions

https://adoptopenjdk.net/releases.html?variant=openjdk16&jvmVariant=hotspot

Dropped Windows 32–bit Client VM: In JDK 9, the Windows 32–bit client VM is not available.
