The following error is given when I try to deploy a simple app (the default one that IntelliJ provides when you create a new Java EE Web App project):

If I try to manually deploy the same .war file in my personal TomEE installation using startup.bat this error does not occur.
I have tried both TomEE 8.0.7 and 8.0.8; this is the pom.xml:

What can possibly be the cause?
You are using Java 16 (as shown in the log file) with Maven. In this case, you should use TomEE in version 8.0.9 as this release contains important fixes regarding illegal reflective access (due to the use of Unsafe for proxy creation) in higher versions of Java. You find some details in https://issues.apache.org/jira/browse/TOMEE-3795
It looks like you are using a lower Java version for running your standalone TomEE deployment, which works as it isn't as restrictive as newer Java versions.
Side Note: Java 16 is end-of-life and you should better switch to Java 17.
