Java Download Hangs Mac Sierra

Mac Sierra Download

Apple社は2016年9月にmacOS Sierraをリリースしました。Javaはこのバージョンと互換性がありますが、SierraでのJavaの問題がいくつか報告されています。これらの問題の特定および解決に向けて積極的に取り組んでいます。. Hi everbody, maybe you can help me out here. I was running the Designer 0.8 on a Mac with Sierra, Java 1.8.112 (i guess) and installed lately Eclipse IDE (most recent version Oxygen 1A) togehter with an update of Java 1.8.152. Since then I cannot use the designer anymore. Soon as the main window has loaded, it becomes completely unresponsive. I even need to force-close it. Clicking on just.

Unable to install Eclipse Oxygen on macOS Sierra due to JRE 6 dependency[message #1769484]

I'm trying to install the latest Eclipse Oxygen release (eclipse-inst-mac64.tar.gz downloaded today) onto macOS 10.12.5 (Sierra). After decompressing the tarball, I have a 'Eclipse Installer.app' that when I open gives me this error:
'To open 'Eclipse-inst' you need to install the legacy Java SE 6 runtime.'
However, according to this page, I should only need JRE 8, not JRE 6.
I have downloaded JRE SE 8u144 from Oracle and installed it, however I still get this error message.
Is it actually correct? Do I really need two different JREs installed to install Eclipse? Why doesn't the installer work with JRE 8?
EDIT: I have confirmed via Safari and oracle.com that v8u144 is 'active' on my system.
EDIT: I see on StackOverflow that the problem might be solved by installing JDK 8 rather than JRE. However I specifically do not with to do this (I will be using Eclipse with CDT, not for Java development) and if it truly is a requirement then I suggest two changes:
1. fix the installer so it works with a modern version of the Java RE.
2. update the docs so that it specifies the JDK as a minimum requirement, rather than the JRE.

Unfortunately each OS has its own peculiarities. The message about needing Java 6 comes from the Mac OS itself, and it's a bogus message. This basic problem affects not just the installer application, but any other Eclipse application you will try to install using it, because the installer application is in fact just an Eclipse application and will suffer from all the same problems that it has. So yes, as far as I understand it, to run any Eclipse application on a Mac, you will need to install a JDK, best a JDK 8 at this point. Not that it's helpful to you, but for Windows, the installer is distributed as a native executable that does smarter checking of the available JREs and JDKs on the system so it does a better job detecting problems you will have when you actually try to launch the application, linking you to a page like this: http://download.eclipse.org/oomph/jre/?vm=2 filtered to the version that's needed when the right JRE/JDK is not available.
Certainly there isn't much useful to explain this Mac-specific peculiarity at https://wiki.eclipse.org/Eclipse/Installation nor in https://www.eclipse.org/downloads/eclipse-packages/?show_instructions=TRUE but I wonder if that's the documentation you think would be best to update, or were you looking elsewhere?

Thanks for the response. I'll install the JDK. The documentation I mentioned was linked in my first post: 'A Java 8 JRE/JDK is required to run all Oxygen packages based on Eclipse 4.7' - perhaps it should include a note to say 'JDK' for macOS?

Sorry, I should have noticed that. I've made a number of changes to the wiki to make the Mac issues explicit.

On the Mac you must install a full JDK. Did you actually install a Java 8 (o higher) JDK (not just a JRE)?

Hi Ed,
I successfully installed Oracle JDK 12 on my Mac - after so many attempts (my antivirus blocked it all the time until I disabled it). I've upgraded to Eclipse 4.11 on Windows (on my older PC), however, it didn't work properly with Java 12 - Java 12 enhancements were not recognized and any Java 12 code was marked as an error.

Did you properly configure the JRE used by the installation in Preferences -> Java -> Installed JREs to specify the Java 12 JDK/JRE? And is Preferences -> Java -> Compiler configured to Java 12?
