Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users.

There is a newer version: 1.7.15

/**
   Template for LiveConnect Tests

   File Name:      number-002.js
   Description:

   When setting the value of a Java field with a JavaScript number or
   when passing a JavaScript number to a Java method as an argument,
   LiveConnect should be able to convert the number to any one of the
   following types:

   byte
   short
   int
   long
   float
   double
   char
   java.lang.Double

   Note that the value of the Java field may not be as precise as the
   JavaScript value's number, if for example, you pass a large number to
   a short or byte, or a float to integer.

   JavaScript numbers cannot be converted to instances of java.lang.Float
   or java.lang.Integer.

   This test does not cover the cases in which a Java method returns one
   of the above primitive Java types.

   Currently split up into numerous tests, since rhino live connect fails
   to translate numbers into the correct types.

   test for creating java.lang.Double objects.
