Review comment:
       No, it will not throw any exception. We tested it as simple jobs and as 
templates. 
   
   JAVA syntax is working in the way that `valueProvider.get() != nul`l is 
never going to be call if `valueProvider != null ` returns false . 
   
   In terms of using `valueProvider.isAccessible()`, it makes to use it instead 
of `valueProvider.get() != null`. Thanks :)
