i have filebeat/logstash/elasticsearch/kibana (6.0.3) version

I tried multi-line with filebeat for sample logs first but its not working

log file  
Exception in thread "main" java.lang.NullPointerException  
at com.example.myproject.Book.getTitle(Book.java:16)  
at com.example.myproject.Author.getBookTitles(Author.java:25)  
at com.example.myproject.Bootstrap.main(Bootstrap.java:14)

filebeat (yml)

filebeat.prospectors:

- type: log  
paths:
  - /var/test.log

multiline.pattern: '^[[:space:]]'  
multiline.negate: false  
multiline.match: after

output.logstash:  
hosts: ["10.38.129.39:5044"]

Output

"message": " at com.example.myproject.Bootstrap.main(Bootstrap.java:14)",  
"prospector": {  
"type": "log"  
}  
}

Not combiing the lines

I suggest you edit your post and move it to the Filebeat category. It's not a Logstash question.
