It does support sealed objects, in fact there is a version of 
initStandardObjects that takes a boolean flag to seal the standard 
library objects. The problem is that only CVS version of Rhino makes 
sealed to mean (property id can not be added or removed; or existing 
property value can not be changed), previously including the last 
release it mean only (property can not be added or removed) which was 
not very useful.
