Hpricot gem can't be used with JRuby 1.1RC1
-------------------------------------------
Key: JRUBY-2008
URL: http://jira.codehaus.org/browse/JRUBY-2008
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Environment: Latest JRuby 1.1RC1
Reporter: Vladimir Sizikov
Priority: Critical
Latest hpricot-java gem (ver 0.6) can't be used with JRuby 1.1 RC1, due to API
changes caused by rev. 4588: "Vars have landed.". Basically,
getInstanceVariable() method has been moved out of IRubyObject to RubyObject,
and some code in hpricot gem depends on it.
Here's a simple example:
{noformat}
require 'rubygems'
require 'hpricot'
require 'open-uri'
# load the RedHanded home page
doc = Hpricot(open("http://redhanded.hobix.com/index.html";))
{noformat}
Leads to:
Exception in thread "main" java.lang.NoSuchMethodError:

Hpricot is a popular and important gem, explicitly supporting JRuby with
jruby-specific gem, and it should work with JRuby 1.1.
Also, hpricot is used in rspec spec tests -- all the more reasons to properly
support hpricot.
