Talend Remote Engine Error on Startup

[BDement]

Hello! I have created an AWS EC2 using the Talend-RemoteEngine-2.13.13 AMI from AWS Marketplace. I have added the text below into the User Data field:

remote.engine.pre.authorized.key=[RE key]
pairing.service.url=https://pair.us.cloud.talend.com

Usually at this point, once I start the server, the remote engine starts up and connects to Talend Management Console without issue. However, our latest attempt to create a new Remote Engine is failing. I checked the log files on the EC2 and see the following error occurs on startup. Any ideas on what this error means and what could be the cause?

Hello 

We clearly needs more information here : 

How did you install the remote engine,, and the version of jdk used to install it 

2.13.13 only supports jdk 17 and if using other ones to start the remote engine, it can creates such issue during bundle init
