OpenSSL::SSL::SSLError in jruby 1.6.7/1.7.0 1.9 mode

Question

I'm running a rails 3 app with jruby 1.7.0 in 1.9 mode, and when one of my file uploading gems tries to make a https connection, it fails with the following exception:

Excon::Errors::SocketError: write would raise (OpenSSL::SSL::SSLError)
    from org/jruby/ext/openssl/SSLSocket.java:626:in `syswrite_nonblock'

I found a similar issue on stackoverflow here: JRuby Heroku Gem, but the suggested answer is run jruby in 1.8 mode which I cannot do since our entire app uses 1.9 features and syntax. Does anybody have any ideas or suggesetions on how to fix or get around this exception?

Thanks.

Answer 1

Ok, so here's my hacky solution:

As this is a Rails project, I created a file called excon_hack.rb and put it in the initializers folder.

module Excon
  DEFAULT_NONBLOCK = false
end

This makes the connection block, which doesn't matter to me, and more importantly, it fixes my error.

Answer 2

Another option is to downgrade jruby-openssl to 0.7.4. I'm not clear yet whether that effectively reverts excon to blocking mode, or just gets non-blocking working.
