Seems there is a work-around (found it here by searching related keywords):
require 'net/protocol'
class Net::BufferedIO
def rbuf_fill
if IO.select [@io], nil, nil, @read_timeout
@io.sysread BUFSIZE, @rbuf
else
raise Timeout::Error.new 'execution expired'
end
end
end
Edit: the work around can't work around some other jruby socket/ssl bug (JRUBY-6516):
#!/usr/bin/env ruby
require 'timeout'
require 'net/https'
class Net::BufferedIO
def rbuf_fill
if IO.select [@io], nil, nil, @read_timeout
@io.sysread BUFSIZE, @rbuf
else
raise Timeout::Error.new 'execution expired'
end
end
end
http = Net::HTTP.new 'encrypted.google.com', 443
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.open_timeout = 60
http.read_timeout = 60
p http.start{ |h| h.request Net::HTTP::Get.new '/' }
This example works OK in "ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]" but always times out in "jruby 1.6.7 (ruby-1.8.7-p357) (2012-02-22 3e82bc8) (OpenJDK 64-Bit Server VM 1.6.0_23) [linux-amd64-java]" 
Edit 2: this seems to work as a work-around (notice the 2nd arg to IO.select):
class Net::BufferedIO
def rbuf_fill
if IO.select [@io], [@io], nil, @read_timeout
@io.sysread BUFSIZE, @rbuf
else
raise Timeout::Error.new 'execution expired'
end
end
end

For some background: sometimes a web service our app depends on gets restarted (or something), but the connections are not closed (or something). This causes our SOAP/HTTPS requests to hang (not do anything forever) and usually the stack trace looks like this:
I'm assuming the timeouts don't kick in (just like in the attached client.rb
). Since I don't have the skills to figure this out myself, I'm hoping someone can at least provide me with a work-around on how to make the timeout work.
Seems
JRUBY-5059(fixed) is a bit similar.
