Here is an overview of the issue:
        Key: JELLY-78
    Summary: Null variables are passed over by scope inheritance
       Type: Bug

     Status: Open
   Priority: Minor

    Project: jelly

If I explicitly assign variable foo a null value in the current scope but it has a value in
some parent scope, findVariable() will bypass the null value in favor of the non-null value
up the chain.

This is because JellyContext.getVariable & findVariable just test the result of variables.get(name)
against null instead of also checking with containsKey like this:

       Object value = variables.get(name);
       if ( value == null
         && !variables.containsKey(name)
         && isInherit() ) {


Perhaps this is an explicit design decision, but I thought it was worth mentioning.
