A DESCRIPTION OF THE PROBLEM :
The default implementation of javax.xml.XmlEventReader consumes the newline frequently found after the StartDocument event of a document. That is to say, a Characters event does not get emitted after the StartDocument event, but does get emitted after other StartElement and EndElement events.

The text:
<?xml version=\"1.0\"?>
<outer>

gets reported as [StartDocument, StartElement] but should be [StartDocument, Characters, StartElement].

This bug also exists in 11. I didn't test 8.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
You can see a Jtreg test that demonstrates the behavior here: https://github.com/openjdk/jdk/compare/master...MariusVolkhart:mv/xmlCharacters

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You can see a Jtreg test that demonstrates the behavior here: https://github.com/openjdk/jdk/compare/master...MariusVolkhart:mv/xmlCharacters
ACTUAL -
The test fails on line 90. The event is actually a StartElement rather than a Characters
