If I try to copy a timestamp field (ex: @timestamp), I get a NullPointerException in mutate filter.
Details to reproduce the issue :

  • Version: Logstash 6.1.1
  • Operating System: Windows 10
  • Config File :
	mutate {
		copy => { "@timestamp" => "@timestamp2" }
	}
  • Sample Data:
    Any event reproduces the issue
  • StackTrace :
Exception in thread "Ruby-0-Thread-9@[agg1]>worker0: C:/Developpement/outils/logstash/logstash-6.1.1/logstash-core/lib/logstash/pipeline.rb:392" java.lang.NullPointerException

I traced this back to core: elastic/logstash#8888
Cloning a LogStash::Timestamp instance results in an empty object. Most operations executed on this "shell" object will trigger a NPE when trying to interact with the inner, now empty, property.

I saw that the fix is already implemented and ready to merge !
Wow, I’m impressed !
