Bug 12731 – JNI conversion to Object[] array doesn't work

• Status: RESOLVED
• Resolution: INVALID
• Component: JavaScriptCore

[David Kilzer (:ddkilzer)]

The "Send object array" test from Bug 12636 throws an exception:

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.

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.
