Mango Installation Stuck at Starting Mango (Windows)

JoelHaggar

Is it possible you only have the jre installed and not the jdk? What is the result of "echo $JAVA_HOME"

Hi mmmmmt,

What are your computer's timezone and language settings?

If you can, can you post the results of the hard kill on a startup without modules?

Hi, I have the same problem with the new version 3.2.0. when I try to boot the ma-start in windows and in Linux, it does not work. I did other way too, in the modules folder, I download the zip modules with every dependency module and restart too but it does not work either. Now, I have installed the version 3.0 and I want to upgrade because I need to use the SVG object like "ma-svg" because of the version 3.0 does not exist. I have Java 8 installed and the version 3.0 is working, then I don't know if the specification have changed or it is a bug in the new version.
Could you tell me what is wrong and how to resolve it?

Thank you in advance.

Hi mmmmt and susana,

I have sent you both an email with a possible solution. Please try it and let me know if it solves the issue!

Hi stensma,

We'll be releasing the fix in 3.2.1 on Monday most likely. I will go ahead and email you the fix too, but you'll want to delete it next time you update.

That sentence is an imperative! You can consult github if you like, but it's a bug. mmmmmt's thread dump is what happens.

3.2.1 was released with this fix and a few other updates.

Hello,

I'm getting the following msg when Starting after performing an upgrade,

"Core upgrade found...
No Jar utility found to extract upgrade, Please manually unzip core upgrade and
restart Mango..."

How do I rectify this please?

Thanks

Hi bux236,

I would expect that to be a path problem. Either you haven't defined JAVA_HOME to point at your JDK root directory, jdk1.8.0_xxx/bin/ is not on your path, or you have installed a JRE instead of a JDK.

Hello,

Thank you for your reply, I have now set JDK in the JAVA_HOME.

I now getting the following errors when trying to run upgrade.bat or mastart.bat

C:\Program Files (x86)\mango automation\bin>upgrade.bat

What am I doing wrong please!?

Many Thanks,

That means there is no ma-priv-3.x.x.jar JAR file in the directories specified on the path output after "Using ... as MA_HOME"

Running upgrade.bat is only sufficient to upgrade anything if you already have the new m2m2-core-3.x.x.zip in your Mango/ directory. Then you would have seen this message from ma-start.bat:

Core upgrade found...

So my guess is something has gone wrong with your upgrading, and you should place an m2m2-core-3.x.x.zip in your Mango/ directory and restart Mango.
