ECMA section 15 Standard Built-in ECMAScript Objects says:

"Every other property described in this clause has the attributes { [[Writable]]: true, [[Enumerable]]: false, [[Configurable]]: true } unless otherwise specified."

Instance property of Error, TypeError, URIError etc. is enumerable in nashorn. Confirmed with other impls. that this property is non-enumerable. (unfortunately this is not covered by test262..)
