Firebase Cloud Functions emulator throws "exited with code: 1" error

I'm trying to setup my local environment for testing firebase cloud functions. I've followed along with their documentation but now bump into the following error:

Error: firestore: emulator has exited with code: 1

I've found other SO threads regarding this issue but none with my specific logs:

i  Starting emulators: ["functions","firestore","hosting"]
⚠  Your requested "node" version "8" doesn't match your global version "12"
✔  functions: Emulator started at http://localhost:5001
i  firestore: Logging to firestore-debug.log
✔  firestore: Emulator started at http://localhost:8080

Error: firestore: emulator has exited with code: 1

The firestore-debug.log file does not really hint me in a direction neither:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/google/cloud/datastore/emulator/firestore/CloudFirestore : Unsupported major.minor version 52.0

Anyone here an idea what's causing this bug?

Just download the newest JDK version from here

In case anyone still struggles with this:

Run your emulators:start command again with --debug at the end to see why the process is crashing, right in the terminal.

On macOS 10.14 I needed to install the latest openjdk and enable it:

brew install openjdk

During installation it will then display instructions on how to enable the openjdk. For me it was:

For the system Java wrappers to find this JDK, symlink it with
  sudo ln -sfn \
    /usr/local/opt/openjdk/libexec/openjdk.jdk \
    /Library/Java/JavaVirtualMachines/openjdk.jdk

In addition of downloading JDK, I also needed to restart the computer.

It is more convenient to use AdoptOpenJDK installer for Windows to get the environment setup automatically.

How to install OpenJDK 11 on Windows?

You will still need to refresh your cmd or powershell to get access to the new environment variables PATH and JAVA_HOME the installer setup.
