SchemaLocation of multiple XSD files

[jpgr79]

I have multiple xsd files in src/main/xsd.

I am trying to chaange the classe name of one of those xsd elements.

<jaxb:bindings schemaLocation="MyRequest.xsd">
<jaxb:bindings node="//xs:element[@name='MY_REQUEST']">
<jaxb:class name="CustomRequest" />
</jaxb:bindings>
</jaxb:bindings>

I am getting the following error:

[ERROR] file:/C:/.../src/main/xsd/global-bindings.xjb [26,46]
com.sun.istack.SAXParseException2; systemId: file:/C:/.../src/main/xsd/global-bindings.xjb;
lineNumber: 26; columnNumber: 46; "MyRequest.xsd" is not a part of this compilation.
Is this a mistake for "file:/C:/.../src/main/xsd/MyRequest.xsd"?

It looks like a bug, because if I use schemaLocation with the absolute path name it works.
if i use in my pom, to point to a single xsd file, schemaLocation also works.

I tried with jaxb-maven-plugin versions 2.2 and 2.5.
