Hey guys,

There is an issue with elasticsearch-service if we update Java and we do not reinstall the elasticsearch-service.

In this key:  
HKEY\_LOCAL\_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\elasticsearch-service-x64\Parameters\Java

There is a Jvm string value which points to for example: C:\Program Files\Java\jdk1.8.0\_45\jre\bin\server\jvm.dll

If you uninstall java u45 and update to a newer java, elastic search service stops working because it has an outdated reference.

We should be pointing to the JAVA\_HOME environment variable so that we can handle the cases of java being updated.
