JRuby regressions 1.4.6 -> 1.5.0

[wvanbergen]

Nokogiri 1.5.0 on JRuby seems to have some regressions:

• Nokogiri::XML::Document.parse('< test />').to_s now no longer includes the encoding in the initial tag. This will cause parse issues later on when using unicode characters,
• I am getting "called decorate on nil" exceptions that are completely unrelated to my code.

The travis CI build: http://travis-ci.org/#!/wvanbergen/adyen/builds/75767
All tests run fine when not using JRuby or when using Nokogiri 1.4.6.

This code below produces a "called decorate on nill" exception in JRuby for me. Works fine in 1.4.6:

process_output= <<END
<test>
 <track type="Image">
 <Format>LZ77</Format>
</test>
END

doc = Nokogiri::XML.parse(process_output)

node = doc.xpath(%{//track[@type='Video']})

puts node.xpath("Format").inspect

I'm very sorry to get back to you so late.

@wvanbergen current pure Java version returns exactly the same result as libxml version for Nokogiri::XML::Document.parse('< test />').to_s . So, it looks the bug has been fixed along with other bug fix(es), at some point.

However, "called decorate on nil" exception still exists there. So, I fixed this bug in rev. 0b8bf4e .

Thanks, @gstark . Your code was very helpful to figure out what caused the bug.
