We are removing temporarily the 'builtinclass' from nsIDOMDOMError in bug 790870, but we need to have a proper way to let chrome JS get these objects from the c++ implementation.

If you remove builtinclass, make sure to go through all DOMError usage in C++ and check if there are any static_casts to the actual implementation, since after removing builtinclass, those casts may become security bugs.

Thanks for the heads up. I checked current c++ usage and could not find any static cast.
