+ * <li>Any other Java object is converted to a JavaScript wrapper,
+ *   which can be used to access methods and fields of the java object.
+ *   Converting this wrapper to a string will call the toString method
+ *   on the original object, converting to a number will call the
+ *   floatValue method if possible and fail otherwise.  Converting
+ *   to a boolean will try to call the booleanValue method in the
+ *   same way.
+ * <li>Java arrays are wrapped with a JavaScript object that understands
+ *   array.length and array[index]
+ * <li>A Java boolean is converted to a JavaScript boolean
+ * <li>Java byte, char, short, int, long, float, and double are converted
+ *   to JavaScript numbers
+ * </ul>
+ * Values passed from JavaScript to Java are converted as follows:<ul>
+ * <li>objects which are wrappers around java objects are unwrapped
+ * <li>other objects are wrapped with a JSObject
+ * <li>strings, numbers and booleans are converted to String, Float,
+ *   and Boolean objects respectively
+ * </ul>
+ * This means that all JavaScript values show up as some kind
+ * of java.lang.Object in Java.  In order to make much use of them,

+        - You can refer to a package like java.lang.i.buried.paul without
+          generating a complaint.  Of course, you'll never be able to refer to
+          any classes through it.
+
+        - An annoying consequence of the above is that misspelling a class name
+          results in a cryptic error about packages.
+
+        - In a browser context, i.e. where applets are involved, figuring out
+          whether something is a class may require looking for it over the net
+          using the current classloader.  This means that the first time you
+          refer to java.lang.System in a js context, there will be an attempt
+          to search for [[DOCBASE]]/java.class on the server.
+    
+        A solution is to explicitly tell jsjava the names of all the (local)
+        packages on the CLASSPATH.  (Not implemented yet.)
