+ *
+ * Date:    01 Feb 2002
+ * SUMMARY: Testing Error.length
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=123002
+ *
+ * NOTE: Error.length should equal the length of FormalParameterList of the
+ * Error constructor. This is currently 1 in Rhino, 3 in SpiderMonkey.
+ *
+ * The difference is due to http://bugzilla.mozilla.org/show_bug.cgi?id=50447.
+ * As a result of that bug, SpiderMonkey has extended ECMA to allow two new
+ * parameters to Error constructors:
+ *
+ * Rhino:        new Error (message)
+ * SpiderMonkey: new Error (message, fileName, lineNumber)
+ *
+ * NOTE: since we have hard-coded the length expectations, this testcase will
+ * have to be changed if the Error FormalParameterList is ever changed again.
+ *
+ * To do this, just change the two LENGTH constants below -
