Description:
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.
