Question about "TypeError: can't convert Hash into Integer" in rubygems on JRuby 1.6.2

Ruby JRuby

Hello,

I am trying upgrade my JRuby (on Rails)
environment version from 1.4.0 to 1.6.2.
(I was running JRuby in 1.8 mode, not 1.9 mode.)
During this work, following errors are occured.

TypeError: can’t convert Hash into Integer

This problem is solved by manually removing ‘, :encoding => “UTF-8”’
in lib/ruby/site_ruby/1.8/rubygems/specification.rb
===part of “def self.load file”===
code = if defined? Encoding
File.read file, :encoding => “UTF-8”
else
File.read file
end

Is there any good solution about this issue?

As you know, JRuby 1.6.2 includes rubygems 1.5.1 already.
I previously used JRuby 1.4.0 with rubygems-update 1.3.5.

For more info related this issue is following URL (This comes from my
guessing)

This isn’t just a problem in jruby.

This is also occurring with ruby 1.8.7 (2009-06-12 patchlevel 174)
[universal-darwin10.0], the parameter aren’t valid for ruby 1.8.

For such a fundamental part of the ruby stack, such a simple bug should
never of been released, wasted many hours figuring this out.

Every single time I upgrade in ruby land stuff breaks, just unlucky or
is there a quality issue!
