Does MWAA uses java Corretto?

Question

Hey,

My company is moving away from Java Corretto and replacing it with OpenJDK. We are suspicious that one of the services, MWAA, uses Corretto because we found it being installed in this repository, but that is the aws-mwaa-local-runner repository in [here](https://github.com/aws/aws-mwaa-local-runner/blob/6bbbc465c4b4266483f552362f9443c8716063a1/docker/script/bootstrap.sh#L47). Since none of our MWAA environments have a startup script and MWAA seems like a black box, does MWAA install Java Corretto by default?

Thank you.

Accepted Answer

Hello,
Just used a `BashOperator` to run command `java --version` in my MWAA environment (Airflow v2.7.2), and it  returned below:

`[2024-02-13, 17:48:09 UTC] {{subprocess.py:75}} INFO - Running command: ['/usr/bin/bash', '-c', 'java --version']
[2024-02-13, 17:48:09 UTC] {{subprocess.py:86}} INFO - Output:

So, to answer your question, MWAA does seem to install Java Corretto by default. I hope this helps.
