           Summary: LiveConnect does not work returning arrays from Java
                    applet to JavaScript
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED

I am having trouble returning arrays of strings from a Java applet to
JavaScript on Safari 3.1.2. It works fine on Firefox 3.0.1.

Here's the documentation on how it's supposed to work:

Here's are two simple files demonstrating the problem. Compile test19.java with
javac test19.java. Under firefox, you will see two diagnostic alerts followed
by "Success!" On Safari the diagnostics will be obviously wrong and then the
script will halt.

test19.html:

<html>
<head>
<title>tests whether applets can return string arrays</title>
</head>
<script type="text/javascript">
       function clicker ()
       {
               var arr;
               arr  = document.test19.test ();
               alert (typeof arr);
               alert (arr.toString ());
               if (arr[0] == "foo" && arr[1] == "bar")
                       alert ("success!");
               else
                       alert ("failure!");
       }
</script>
<body>
<button onclick="clicker ()">Write Config</button>
<applet name="test19" code="test19.class" width="1" height="1"
mayscript></applet>
</body>
</html>

test19.java:

import java.applet.Applet;

public class test19 extends Applet
{
       public void init () { }

       public void start () { }

       public void stop () { }

       public void destroy () { }

       public String [] test ()
       {
               String [] ret = new String[2];
               ret[0] = "foo";
               ret[1] = "bar";
               return ret;
       }
}
