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
Running upgrade script...

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.
