When parsing a WSDL from an external source containing a Byte Order Mark (BOM) below exception is thrown.

I have managed to work around the problem with this modification to method resolveAsString(url) in com.predic8.xml.util.ExternalResolver.groovy - starting at line 99:

before

EntityUtils.toString(con.entity)

after

String entity = EntityUtils.toString(con.entity)
if(!entity.startsWith("<")) {
    entity = entity.replaceAll("^[^<]+","")
}
entity

I am not confident that this is the proper solution in all cases though.

The exception thrown:

Message: Content is not allowed in prolog.:URL:http://chub-test.tdk.dk/chub.order/services/OrderService?wsdl
Exception in thread "main" javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
