I am trying to configure the logstash to my ELK stack and i keep running into this error.  
I have Java version 8.

D:\workplace\Elasticsearch\logstash-7.4.0\>cd bin

D:\workplace\Elasticsearch\logstash-7.4.0\bin\>logstash -e 'input{stdin{}}output{stdout{}}'

Thread.exclusive is deprecated, use Thread::Mutex
