I am running jruby 1.6.1 in ruby 1.9 mode and when i run this code:

require ‘active_resource’

class EmailAccount < ActiveResource::Base
self.site=“http://localhost:3000”
end
EmailAccount.find(23)

I get:

The above does not happen if i run in jruby 1.8.7 mode.

I am using:

2.6.32-305-ec2 #9-Ubuntu
java version “1.6.0_18”
OpenJDK Runtime Environment (IcedTea6 1.8.1) (6b18-1.8.1-0ubuntu1)
OpenJDK 64-Bit Server VM (build 16.0-b13, mixed mode)

Thx

Ok, i had a stab at looking into the problem myself this morning and I
learned a few things. It looks like the problem is the extra encoding
arg to the ZLIB::GzipReader constructor.

request(Get.new(path, initheader)) {|r|
if r.key?(“content-encoding”) and @compression
@compression = nil # Clear it till next set.
the_body = r.read_body dest, &block
case r[“content-encoding”]
when “gzip”
r.body= Zlib::GzipReader.new(StringIO.new(the_body),
encoding: “ASCII-8BIT”).read
r.delete(“content-encoding”)
when “deflate”
r.body= Zlib::Inflate.inflate(the_body);

If i change it to this:

request(Get.new(path, initheader)) {|r|
if r.key?(“content-encoding”) and @compression
@compression = nil # Clear it till next set.
the_body = r.read_body dest, &block
case r[“content-encoding”]
when “gzip”
r.body= Zlib::GzipReader.new(StringIO.new(the_body)).read
r.delete(“content-encoding”)
when “deflate”
r.body= Zlib::Inflate.inflate(the_body);
r.delete(“content-encoding”)
when “identity”

Then things seem to be ok. Coincidentally, my change matches with the
MRI ruby 1.9.2 http.rb file.

So Karl, do you think this is still a JRuby compatibility issue with
1.9 net/http? I couldn’t quite tell from your followup. If so, please
file this as a bug at http://bugs.jruby.org.

Thanks,

this?

Yeah, good catch. We’ve not yet implemented optional hash arg for
GzipReader…

Sorry for confusing you. Please do so. It would not be a simple
monkey-patch thing so we should track the progress of fix.
