JInternalFrame glasspane anomoly between Java 5 and Java 6

FULL PRODUCT VERSION :
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :

Microsoft Windows XP [Version 5.1.2600]


A DESCRIPTION OF THE PROBLEM :
There is a descrepancy in the behavior of a JInternalFrame
glass pane between Java 5 and Java 6.


I have an application that has JDesktopPane in which Several
JInternalFrame subclasses are added.

The JInternalFrame subclass installs a GlassPane thusly:

       setGlassPane(new Component() {
            public void setVisible(boolean b) {
                super.setVisible(false);
            }
        });

The goal is to prevent the frame from being raised when
the user click on a component in the
content pane, but do raise the frame when the title bar
or frame handles are clicked.


Under Java 5 this would prevent the JInternalFrame from
being raised when the mouse was clicked in the content
area of the internal frame. Our application had several
integrated features that rely on the internal frame not being
raised during user interaction. But would be raised when
the user clicks on the title bar of the internal frame.

The behavior that we are emulating is similar to the X
windows feature of the focus following the mouse but with
out the internal frame gaining focus or raising when the
mouse enters the internal frame or is clicked on the
content area.

A program is provided.

When executed under Java 5 clicking on the button in the
internal frame invokes the button but does not raise the
frame.

When executed under Java 6. The frame is always raised.

The desired behavior is that the frame is raised only when
the title bar or frame handles are clicked.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the provided program under Java 5.

2. Click button in lower frame. Frame does not raise.

3. Run the provided program under Java 6.

4. Click the button in the lower frame. Frame raises.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Lower frame does not raise when content pane components are clicked.
ACTUAL -
Lower frames raises when content pane components are clicked.

REPRODUCIBILITY :
This bug can be reproduced always.
