Crash logstash after updating from 5.3 to 5.5

[b2ron]

I have
CentOS release 6.9
logstash 5.3.3-1
java version "1.8.0_92"

I'm trying to update to logstash 5.5.
After the update, the logstash does not start, and in the logs

[2017-07-07T12:02:47,540][FATAL][logstash.runner ] An unexpected error occurred! {:error=>#<NameError: undefined local variable or method dotfile' for #<AwesomePrint::Inspector:0x69942950>>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/1.9/gems/awesome_print-1.8.0/lib/awesome_print/inspector.rb:163:inmerge_custom_defaults!'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/awesome_print-1.8.0/lib/awesome_print/inspector.rb:50:in initialize'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/awesome_print-1.8.0/lib/awesome_print/core_ext/kernel.rb:9:inai'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-codec-rubydebug-3.0.3/lib/logstash/codecs/rubydebug.rb:39:in encode_default'", "org/jruby/RubyMethod.java:120:incall'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-codec-rubydebug-3.0.3/lib/logstash/codecs/rubydebug.rb:35:in encode'", "/usr/share/logstash/logstash-core/lib/logstash/codecs/base.rb:50:inmulti_encode'", "org/jruby/RubyArray.java:1613:in each'", "/usr/share/logstash/logstash-core/lib/logstash/codecs/base.rb:50:inmulti_encode'", "/usr/share/logstash/logstash-core/lib/logstash/outputs/base.rb:90:in multi_receive'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/single.rb:15:inmulti_receive'", "org/jruby/ext/thread/Mutex.java:149:in synchronize'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/single.rb:14:inmulti_receive'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator.rb:47:in multi_receive'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:420:inoutput_batch'", "org/jruby/RubyHash.java:1342:in each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:419:inoutput_batch'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:365:in worker_loop'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:330:instart_workers'"]}

I would be grateful for the help.
Thanks

What's your config look like?

I too am having this issue.

OS: Amazon Linux 2017.03
Logstash: 5.5.0-1
JDK: 1.8.0_131

1 and only config . in /etc/logstash/conf.d/

input {
   file {
      path => "/shared/prod_elb_logs/**/*"
      type => "elb"
      start_position => "beginning"
      sincedb_path => "/shared/.prod_elb_logs_since.db"
      }
}

filter {
    if [type] == "elb" {
        grok {
            match => [ "message", "%{TIMESTAMP_ISO8601:timestamp} %{NOTSPACE:loadbalancer} %{IP:client_ip}:%{NUMBER:client_port:int} %{IP:backend_ip}:%{NUMBER:backend_port:int} %{NUMBER:request_processing_time:float} %{NUMBER:backend_processing_time:float} %{NUMBER:response_processing_time:float} %{NUMBER:elb_status_code:int} %{NUMBER:backend_status_code:int} %{NUMBER:received_bytes:int} %{NUMBER:sent_bytes:int} %{QS:request}" ]
        }
        date {
            match => [ "timestamp", "ISO8601" ]
        }
    }
}

output {
   elasticsearch { hosts => ["172.31.45.27:9200"] }
   stdout { codec => rubydebug }
}

Crashes if I apply such a filter

filter {
  if [type] == "postfix-events" {
        grok {
            patterns_dir => ["/etc/logstash/patterns.d"]
            match => { "message" => ["%{PF}"] }
        }
        date {
            match => [ "timestamp", "MMM dd HH:mm:ss" ]
        }
    }
    # monitor metrics and health of logstash
    metrics {
        meter => [ "events" ]
        add_tag => "metric"
    }
}

and I have fields with dots.
But in version 5.3, this did not cause a crash.

you'd better comment out stdout { codec => rubydebug }
