XML response with UTF-8 BOM causes SAXParseException when unmarshalling for jaxb

    Details

      Description

      I'm calling a REST api running on Windows server, which returns a UTF-8 encoded xml starting with a BOM. With Resteasy 3.0.8.Final this works fine, but with 3.0.9.Final an exception is thrown on unmarshalling.

      The response looks like this:
      [DEBUG] wire - << "[0xef][0xbb][0xbf]<?xml version="1.0" encoding="utf-8"?><Version xmlns="urn:eventis:prodis:onlineapi:2.0">v2_12</Version>"

      The exception:

      Caused by: org.jboss.resteasy.plugins.providers.jaxb.JAXBUnmarshalException: javax.xml.bind.UnmarshalException
       - with linked exception:
