Rhino 1.7.7.2

Table of contents

---

This release contains fixes for a few important bugs that have caught Rhino users out in the field.

• Do not throw a Java exception from array.prototype.sort() no matter how weird the user-supplied comparator function is. This is a major difference between JavaScript and Java and has caused us to avoid using “Arrays.sort” on JavaScript arrays.
• Fix incorrect offsets in the “DataView” class.

It also includes several other fixes:

• Always append a column number to V8-style stack traces. (Unfortunately it is always “0”.)
• Support Object.is and Object.assign.
• Make the Symbol implementation match the spec (for VERSION_ES6 and up only).
• Avoid throwing internal Java exceptions for certain native objects in “toJSON”.
• Allow subclassing of ContinuationPending.
• For VERSION_ES6 and up, sort properties in the spec-defined order (int property names first).
• Fix stack overflow in string concatenation.
• Improve performance of ConsString.toString

The next release is likely to be 1.7.8.
