Description David Kilzer (:ddkilzer) 2007-02-10 20:46:11 PST 
The "Send object array" test from Bug 12636 throws an exception:

Comment 1 David Kilzer (:ddkilzer) 2007-02-10 20:48:24 PST 
Also I think this method in ArrayParameterTestApplet.java:

    public void objectFunction(Applet[] array) {

should look like this:

    public void objectFunction(Object[] array) {

Changing this still doesn't fix the issue, though.
Comment 2 David Kilzer (:ddkilzer) 2008-07-06 19:50:33 PDT 
This behavior isn't wrong, it's one of the tests to make sure that WebKit doesn't crash when using a non-String array argument.
