Quarkus2 prints null when started using ant target

[Postremus]

Describe the bug

When I run a quarkus 2.0.0.Final app using an ant target, I get 2 lines simply stating "null".

This is most likely related to the

Expected behavior

When run in a terminal, these 2 nulls are empty lines.

Actual behavior

To Reproduce

Link to a small reproducer (preferably a Maven project if the issue is not Gradle-specific).

Or attach an archive containing the reproducer to the issue.

Steps to reproduce the behavior:

1. Download the reproducer:
   ant-null.zip

2. IDEA: Open the build.xml file in the editor, right click on the content, add as ant build file

3. You should now have a new view on the right side called "ant"

4. Execute the mvn_quarkus:dev_local target by double clicking it

It's the same with #18287 . I got the same issue as well

This is basically a duplicate of #18287, so I'm going to close this.
The problem is fixed in main (Quarkus 2.1), but the PR was flagged for backporting so it might end up in 2.0.x.
Thanks for reporting!
