>
> When MapVariableInterpolator interpolates a string that contains variables
> missing in the variable map, it throws a NPE even if exceptionOnNullVarValue
> is set to false. The bug is in the getValue method - toString() is invoken
> directly on tha value returned from the map.
> A trivial patch is attached.
