JRUBY-2211 fix doesn't work if the destination machine is up but the
destination port is down.
-----------------------------------------------------------------------------------------------
Key: JRUBY-4627
URL: http://jira.codehaus.org/browse/JRUBY-4627
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.4
Environment: Windows XP
P4 2.4 Ghz
JRuby 1.4.0
SNMP gem v1.0.2
Reporter: nao16t
Fix For: JRuby 1.5
JRUBY-2211 fix works OK if the destination machine is down.
However JRUBY-2211 fix doesn't work if the destination machine is up but the
destination port is down.
Please compare the following results between CRuby 1.8.6 and JRuby 1.4.0.
snmptest.rb is attached JRUBY-2211. I changed only IP address.
JRuby's UDPSocket#recv hangs up but CRuby's returns Errno::ECONNRESET.
And the fourth argument of JRuby's UDPSocket#send has to be Integer, but
CRuby's can be either String or Integer.
