Parse error in "arquillian.xml" with non-ascii chars

[WolfgangHG]

Attached sample is created from the archetype "wildfly-jakartaee-webapp-archetype" and works fine. But when adding any UTF8 char to "arquillian.xml" (e.g. an umlaut like "ä" in any comment), it fails to parse this file:

<arquillian xmlns="http://jboss.org/schema/arquillian" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://jboss.org/schema/arquillian
                                https://jboss.org/schema/arquillian/arquillian_1_0.xsd">
    <!-- ä-->
    ...
</arquillian>

The error message is "invalid byte 2 of a 3-byte utf-8 sequence":

[Fatal Error] :4:9: Ungültiges Byte 2 von 3-Byte-UTF-8-Sequenz.

To reproduce:

1. You need a running WildFly 35 server (https://github.com/wildfly/wildfly/releases/download/35.0.0.Final/wildfly-35.0.0.Final.zip)
2. Launch the sample like this:
   mvn.cmd -Parq-remote verify
   The build/test should run without error in the original sample, but it should fail if "arquillian.xml" is manipulated.

This is an old issue, but as there seems to be a bit of activity in this project, I want to bring it back to your attention. Here is the original issue - does not even exist in the JBoss JIRA: https://web.archive.org/web/20200512135200/https://issues.redhat.com/browse/SHRINKDESC-97
