Hi,

When installing gems in Windows with jruby the majority of the time I get the following error:

C:\data\BrandonH\Dev>jruby -S gem install arel
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
SystemCallError: Unknown error - An established connection was aborted by the software in your host machine (http://gemcutter.org/gems/i18n-0.3.6.gem)

When doing a gem install in Windows in MRI I have no problems. This problems seemed to start in the last month or two after no changes on my local machine. It makes no difference rather I am using jruby 1.4.0 or the master branch. I have rubygems 1.3.6 installed in both.

   Can you run gem install [some gem] -V ? The --debug flag output will help us out too.

   Also, are you behind any kind of firewall or NAT? We've heard of some issues with that.

   Hi,

   I am not behind a firewall or NAT. This same command works fine in MRI, and only just recently broke in JRuby.

   Here is the output with -V and --debug

   Sounds like jruby is not mapping this exception to Errno::ECONNABORTED, from rubygems/remote_fetcher:

   # NOTE Errno::ECONNABORTED raised a lot on Windows, and make impossible
   # to install gems.

   drbrain or Nick,

   Why would this error just start recently w/ no changes to jruby? Where there changes to rubygems recently? I can report this to the jruby team, but they might need more information on how to go forward.

   Thanks,

   Brandon Hauff

   Fixed in commit 6e8d0d5 in JRuby.

   The base issue here was that IO.sysread was returning a generic unknown Errno Exception instead of ECONNABORTED errno. drbrain nailed it.

   Thanks Tom!

   Brandon: The behavior I'd heard of about Errno::ECONNABORTED is that it just happens sometimes because that's how Windows built their TCP/IP stack. Maybe the connection between you and rubygems.org is more congested, or some TCP timeout was tripped.
