Java activities

I would like to run a jar file in UiPath. Using start process activity, it is working well. But when I use Java Scope and load jar activity it is not working. Also I set the path correctly as mentioned. Please check this error screen shot.

18.3.0+Branch.master.Sha.e9cf0bdab85f4bcf826ce750c59905c7ac073d5e

Source: Java Scope
