Major divergence in threading behaviour between Ruby 1.8.6 and JRuby 1.1.6
--------------------------------------------------------------------------
Key: JRUBY-3329
URL: http://jira.codehaus.org/browse/JRUBY-3329
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.6
Environment: Ubuntu 8.04, Java 1.6.0_10, x86 32-bit, JRuby 1.1.6
Reporter: Michael T. Richter
The following very simple test case works in Ruby 1.8.6pl111 and fails in JRuby
1.1.6:
require 'net/telnet'
require 'thread'
puts host=(ARGV[0] || 'london.ginkosoft.com')
puts port=Integer((ARGV[1] || 2007))
server = Net::Telnet.new('Host' => host, 'Port' => port, 'Waittime' => 0.1)
outputthread = Thread.new do
loop do
server.waitfor('Match' => /.*/) {|output| print output}
end
end
loop do
input = STDIN.gets
server.write input
end
outputthread.join
The error when running this with jruby happens after the STDIN.gets call:
