XJC fails when backslash in schema import and bindings specified

I want to generate Java classes from an XSD with xjc (version 2.3.0-b170531.0717)

Unfortunately the XSD imports another XSD given in a relative path with Windows path separators (backslash \), which is stated as an excluded character according to RFC-2396 in xsi:schemaLocation backslash not allowed?

When running just xjc, the schema compiles fine. But I want to specify some bindings with the command line parameter -b bindings.xjb and then the backslashes become a problem resulting in an failing the schema parse.

How can I get around this issue? I have tried using a catalog to resolve the paths but it seems to fail prior to the catalog use.

Minimal working example

a.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:b="b.xsd"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema"
        elementFormDefault="qualified">
    <xsd:import namespace="b.xsd" schemaLocation=".\b.xsd"/>
</xsd:schema>

b.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="b.xsd"
    elementFormDefault="qualified"/>

c.xjb

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings
    xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
    xmlns:xs="http://www.w3.org/2000/10/XMLSchema-instance"
    xs:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
    jaxb:version="2.0" />

console output

> xjc a.xsd
parsing a schema...
compiling a schema...

> xjc a.xsd -b c.xjb
parsing a schema...
[ERROR] Unable to parse ".\b.xsd" : File name is not an URI. Illegal character in path at index 1: .\b.xsd
  line 3 of a.xsd

Failed to parse a schema.

EDIT: With xjc -verbose I get the following StackTrace, stating it's a problem coming up from Java's URI class being standard conform and thus rejecting backslashes.
