I try to update logstash to 2.3.  
When i run command

> /opt/logstash/bin/logstash -f /etc/logstash/conf.d/ --configtest

and got error

> `An unexpected error occurred! {:error=>#<NoMethodError: undefined method`config\_valid?' for LogStash::Pipeline:Class\>, :class=\>"NoMethodError", :backtrace=\>["/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.0-java/lib/logstash/agent.rb:169:in `execute'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.0-java/lib/logstash/runner.rb:94:in `run'", "org/jruby/RubyProc.java:281:in `call'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.0-java/lib/logstash/runner.rb:99:in `run'", "org/jruby/RubyProc.java:281:in `call'", "/opt/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/task.rb:24:in `initialize'"], :level=\>:warn}`
