Not generating any classes for given wsdl file

I have two files. One works fine with the jaxb plugin for maven but the other one does not generate any classes. However, other services have no problem to recognise the file as a soap wsdl file.

When using the following file, it only generates a `sun.jaxb.episode` file. No error is thrown but no classes are generated either.

pom.xml:

```xml



org.jvnet.jaxb2.maven2
maven-jaxb2-plugin
0.14.0



generate




${project.basedir}/src/main/resources/wsdl

*.wsdl





```

wsdl-file:
```xml

```

When using a [differently formatted wsdl file][1], it generates the classes fine. So the problem seems to be with JAXB in combination with my wsdl-file. Any ideas why it cannot generate any java classes?
