Mozilla Rhino JavaScript engine is used to implement reference JavaScript engine with javax.script API (JSR 223). Mustang initially used Rhino 1.5R5. After 6314058, we changed that to Rhino 1.6R1. Recently, Mozilla has released Rhino 1.6R2. (http://www.mozilla.org/rhino/rhino16R2.html). We would like to use the latest possible version of Rhino engine in JDK.
