Errors/Warning compiling a WSDL file - but the generated Java sources are ok

First: Thanks for all the new contributions to the project!

I have tried to update a project which creates java sources from a WSDL. Unfortunately I see the following exception on invoking the compiler:

[INFO] Sources are not up-to-date, XJC will be executed.
[WARNING] Error while parsing schema(s).Location [].
org.xml.sax.SAXParseException; Versuchen Sie, WSDL zu kompilieren? Unterstützung für WSDL ist zu Testzwecken bestimmt. Eine Aktivierung ist mit der Option -wsdl möglich.

...

The exception asks something like "Do you try to compile WSDL? Support for WSDL is for test purposes. You can activate it with the option -wsdl.

With version 0.14.0 everything was working without that message. However, the tool creates the Java-Codes as expected!

The relevant section in my pom.xml is:

I’ll take a look at it this weekend. Seems odd since the root of the stack trace is the xjc layer.

com.sun.tools.xjc.ModelLoader.load

I’ve noticed the same exception but all the sources were generated on JDK 17. I’ve noticed no change after adding

<args>
   <arg>-wsdl</arg>
</args>
