Downloaded camunda-bpm-ee-wildfly-7.15.4-ee.zip and running ./start-camunda.sh in Mac OSX Big Sur

I get:

./start-camunda.sh

openjdk 16.0.1 2021-04-20
OpenJDK Runtime Environment Homebrew (build 16.0.1+0)
OpenJDK 64-Bit Server VM Homebrew (build 16.0.1+0, mixed mode, sharing)

or how to set java to version that is supported only for this local project in ~/.zshrc?

From the Supported Environments document, Java 16 isn’t supported yet.

Try downgrading your Java.
There’s been a lot of success reported with Java 8

Thanks @GotnOGuts

Says OpenJDK 8 / 9 / 10 / 11 / 12 / 13 / 14,

so how do we download to OpenJDK 14 just for this folder?

I don’t actually have access to a Mac, so can’t really be much help there.

But…

  1. Do you have another Java version installed?
  2. You should (no promises) be able to do “JAVA_HOME=/path/to/JDK14 ./start-camunda.sh” (without quotes)

Hello @scheung38 ,

I can recommend Jenv for managing multiple JDK installations on your Macbook.

Are you familiar with using Command Line? If yes, this little guide can help you getting started with Jenv:

I hope this helps

Hi @scheung38,

you can ignore this:

With JDK 14, Javascript Nashorn is still there.

Hope this helps, Ingo
