<![CDATA[Mango 4.0 - web server error on Windows 10 Pro]]>Hi, Mango Team
I have a freshly installed Windows 10 Pro with OpenJDK Version 11. I have no problem running Mango 3.7.7. However, for Mango 4.0, no matter running it manually or from windows service mode, it always comes up with a http error 503 message.
Attached are two screenshots - one showing the windows service has been enabled and running ok and the other showing the error message.
Can you please check?

Do I need Oracle JDK or OpenJDK for Mango 4.0 to work on windows 10 Pro?

sorry, I don't check the docu v4...

I have installed on a WIN10PRO PC AdoptOpenJDK 11.0.8.10 x64 - not Oracle! - install the service via cmd as Admin switch to the mango folder "boot" and run "java -jar ma-windows-service.jar install" and Mango 4.0 beta 3 is runing via service.
No problems, all works fine!

Same error when manually execute the program as per the instructions on the website:

javaws.jar is not included in AdoptOpenJDK which is required for YAJSW to work.

I think that's the reason.

My last productive 4.0 installation runs with this solution:
