Sub Tasks

Description
This scenario caught a regression w.r.t. 6UR. Javascript calls a applet method which returns a java object but with present behavior the returned java object is not getting passed onto the calling javascript. e.g. following call inside the html
var props = app.getSystemEnvironment(), should return java.util.Properties, but in actual nothing is getting returned
- Try loading the following applet inside the browser

- If you can notice above mentioned behavior then bug is reproduced

EVALUATION

The IE JavaScript engine expects that a COM property fetch with a
DISPID of 0 corresponds to a "toString" operation. Recognized and
re-dispatched this properly. Also converted to using ReflectUtil in
JavaClass to avoid invoking methods with inaccessible holder classes
when those methods were implementations of those in a public interface
or abstract class.

The test case itself has bugs; it expects that JavaScript arrays are
automatically converted to Java arrays, which is not the case in the
old IE plugin and is also not yet the case in the new plugin, although
we might consider making this change (portably, across browsers).
Commenting out the portion of the test case which attempts to use
reflection from JavaScript allows it to pass. A new bug will need to
be filed about this particular issue.
