References from object treated as local, break pdf

See original GitHub issue

Expected Behavior

I’ve got the following object element:

<object data="https://www.youtube.com/embed/BaUjhYw8IK4" width="640" height="480" props="kc">
<desc>Sample video</desc>
</object>

For HTML, I expect this to render proprely as <object>, which it does in 2.5 and 3.0. For PDF, I expect to at least get a PDF, whether or not any video link appears.

Actual Behavior

In DITA-OT 2.5.4 this generates errors in the copy-html step: [copy] Failed to copy https://www.youtube.com/embed/BaUjhYw8IK4 to C:\DCS\2.5.4\test\object\outot25\https:\www.youtube.com\embed\BaUjhYw8IK4 due to java.io.FileNotFoundException C:\DCS\2.5.4\test\object\outot25\https:\www.youtube.com\embed\BaUjhYw8IK4 (The filename, directory name, or volume label syntax is incorrect.)
In DITA-OT 3.0, the HTML5 build begins generating errors in gen-list and actually writes the full linked file into the log, beginning with:

 [gen-list] Processing https://www.youtube.com/embed/BaUjhYw8IK4
 [gen-list] Warning at xsl:stylesheet on line 6 column 31 of utils.xsl:
 [gen-list]   Stylesheet module classpath:///utils.xsl is included or imported more than once. This is
 [gen-list]   permitted, but may lead to errors or unexpected behavior
 [gen-list] <html lang="en" dir="ltr" data-cast-api-enabled="true"><head><meta name="viewport" content="width=device-width, initial-scale=1"/>.....

In DITA-OT 2.5.4, for PDF, I just don’t get any output for the <object> which is probably expected? But I also get the errors in copy-html step.
In DITA-OT 3.0 I get a build failure from preprocess2 during topic-reader:

Error: java.nio.file.InvalidPathException: Illegal char <:> at index 5: https:\www.youtube.com\embed\BaUjhYw8IK4

Possible Solution

The workaround is to use @datakeyref, and on the key definition set scope="external". But, we shouldn’t be crashing (and I’ve got a lot of objects coded like this in older material). Not sure of the code solution.

Steps to Reproduce

Samples attached - build to html5 or pdf to reproduce. Samples include the broken <object> as well as one that uses keys to get better results: object.zip

Environment

DITA-OT version: 2.5.4, 3.0
Operating system and version: Windows 7
How did you run DITA-OT? dita command
Transformation type: html5, pdf

Offtopic The followng Ant snippet downloads the YouTube teaser image. Maybe this helps someone, who wants to use it as a placeholder in PDF:

<?xml version="1.0" encoding="UTF-8"?>
<project name="YouTubeAnt" default="all">
    
    <macrodef name="getYouTubeTeaserImage">
        <attribute name="url"/>
        <attribute name="dest"/>
        <sequential>
            <property name="youtube-url" value="@{url}"/>
            <script language="javascript">
                <![CDATA[
                    var youtubeURL = YouTubeAnt.getProperty("youtube-url");
                    var delimIndex = youtubeURL.lastIndexOf('=');
                    var youtubeID = youtubeURL.substring(delimIndex + 1, youtubeURL.length());
                    YouTubeAnt.setProperty("video-id", youtubeID);
                ]]>
            </script>
            <get src="http://img.youtube.com/vi/${video-id}/0.jpg" dest="@{dest}"/>
        </sequential>
    </macrodef>

    <target name="all">
        <getYouTubeTeaserImage url="https://www.youtube.com/watch?v=h7OyOsFv5AQ" dest="teaser.jpg"/>
    </target>
</project>
