Error :

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

scenario :

Few hours before pentaho was running fine on machine, after changing the version of libraries, bat files and plugins i was facing above error.

So i was pretty sure about error is not related to OS version or java

Solution:

I decreased the Xmx1024m to Xmx512m in spoon.bat, it worked
