Class StringPrimitivePrototypeBugFixer

java.lang.Object

com.gargoylesoftware.htmlunit.javascript.StringPrimitivePrototypeBugFixer

All Implemented Interfaces:

org.mozilla.javascript.Scriptable

public class StringPrimitivePrototypeBugFixer
extends Object
implements org.mozilla.javascript.Scriptable

Implements a workaround for Rhino bug https://bugzilla.mozilla.org/show_bug.cgi?id=374918. Once this bug is solved, this class can be safely removed. Unit tests will ensure that this works correctly.
Bug Description: string primitive prototype is badly resolved when many top scopes are involved.
Workaround: a custom prototype is placed on the String object. It wraps the original one and fix bad scope resolution when needed. For this purpose it needs to change the visibility of some Rhino private members to access them and is likely to get broken on Rhino version updates.
