How do I debug: javax.xml.bind.JAXBException: - not a valid property on class after changing wsdl/xsd

Introduction

Hi, I had a project that was working perfectly.

I am using apache cxf and the generated client code was working perfectly.

However, since yesterday I downloaded new versions of the WSDL and XSD and it seems to be failing.

Configuration

My plugin pom.xml entry is the following:

<plugin>
                <groupId>org.apache.cxf</groupId>
                <artifactId>cxf-codegen-plugin</artifactId>
                <version>2.7.3</version>
                <executions>
                    <execution>
                        <id>generate-sources</id>
                        <phase>generate-sources</phase>
                        <configuration>
                            <sourceRoot>${basedir}/src/main/java</sourceRoot>
                            <wsdlOptions>
                                <wsdlOption>
                                    <wsdl>
                                        ${basedir}/src/interface.wsdl
                                    </wsdl>
                                </wsdlOption>
                            </wsdlOptions>
                        </configuration>
                        <goals>
                            <goal>wsdl2java</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Stacktrace

And the error I am getting is the following:

Questions

1. How do I debug this?
2. Is it due to some inconsistency in the new wsdl and xml files?
3. The code was working fine previously.

I cannot upload the wsdl and xsd files as they are confidential.

Update

I noticed that one change has been the following:

The working definition created a java comment like:

*         <element name="trans" type="{http://server/}trans" minOccurs="0"/>

And now the broken one does the following:

*         <element name="trans" type="{http://server/}trans" minOccurs="0" form="qualified"/>
