Don't make null convertible into anything

           Summary: Don't make null convertible into anything
           Product: Commons
           Version: 1.0 Final
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: JEXL
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: paul@activemath.org


Currently JEXL is very tolerant with null (and unresolved variables)... 
I am unsure now but I think null will become false if the output of a test, null will become the empty 
string if concatenated to a string, null will become the number zero when added. Moreover, 
invoking a method on null gives you... null...

I would love a switch that just disables all this (I think this would impact quite a lot) allowing my jexl 
snippets to be quite more predictable!
