I have installed elasticsearch 2.2.0 and it worked fine for a week, but now it didn't start. I have set both JAVA\_HOME and JRE\_HOME. I use java version 1.8 (i.e., jdk1.8.0\_201 and jre1.8.0\_202). When I try to start the elasticsearch.bat it terminates with a error message of:
```auto
Exception in thread "main" java.lang.NoClassDefFoundError:

```
But no logs has been generated.

Why are you using such an old version?
