REXML::Document.parse_stream doesn't handle when closing tag not provided

Description

I've tried to use REXML for parsing but got unexpected behavior:

Here is example:

require 'rexml/document'
require 'rexml/streamlistener'

class Handler include REXML::StreamListener end

xml1 = StringIO.new("<body><item>test</item></body>")
xml2 = StringIO.new("<body><item>test</body>")
xml3 = StringIO.new("<body><item>test</item>")

handler = Handler.new

REXML::Document.parse_stream(xml1, handler) # => nil
REXML::Document.parse_stream(xml2, handler) # => REXML::ParseException: Missing end tag for 'item' (got "body")
REXML::Document.parse_stream(xml3, handler) # => nil

Actualy XML: "

test" is broken so it's expected to get: 
REXML::ParseException.new( "Missing end tag for body")

I can't rely on REXML parse since I'm not getting exception when XML data structure not valid.
