@nagarjun1, that's a pretty strange error that implies a pretty low-level incompatibility in one of the Java classes used in Logstash core (i.e., `MessageDigest.digest()` is returning a `String` rather than a `byte[]`). I do not get this error when running LS 6.7.0 with Oracle Java 1.8.0\_201-b09 on Windows Server 2016. Do you have anything in your `CLASSPATH` environment variable or anything unusual in your Logstash pipeline definition? ---

> [@danhermann](#): > > `CLASSPATH` The Java path is set as : JAVA\_HOME=C:\Program Files\Java\jdk1.8.0\_201. Using the default config file : logstash-sample.conf. unfortunatley im not able start the logstash from command prompt also. ---
