Removing the Socket::Option.bool line

[aabed]

while using Jruby I get this error
and I've opened an issue on jruby repo and here is their response
jruby/jruby#2997
if it's not essential, can you please remove it and update the gem?

Thanks,

logstash-input-hpfeeds doesn't currently work out of the box because of this (i have to patch out the invocation).

It looks like its 'fixed' upstream in jruby/jruby#2997 however logstash are on jruby 1.7.x at present so it's still broken for logstash users.

@vicvega would you merge a patch that added something like this?

begin
    @socket.setsockopt(Socket::Option.bool(:INET, :SOCKET, :KEEPALIVE, true))
rescue ArgumentError => e
    @logger.warn("Could not set socket keep alive - running on old JRuby?")
end
