JRuby-Nokogiri does not recognise attributes inside namespaces

[denisdefreyne]

Steps to reproduce

input = <<-XML
<foo xmlns="http://example.org">
  <bar><a href="/foo">baz</a></bar>
</foo>
XML

require 'nokogiri'
doc = ::Nokogiri::XML.fragment(input)
p doc.xpath("descendant-or-self::ex:a/@href", { 'ex' => 'http://example.org' })

Expected output

This is the output on MRI:

% ruby test.rb
[#<Nokogiri::XML::Attr:0x3ff349052644 name="href" value="/foo">]
%

Actual output

This is the output on JRuby:

% ruby test.rb
[]
%
