Description
FULL PRODUCT VERSION :
Java Plug-in 1.6.0_10
Using JRE version 1.6.0_10 Java HotSpot(TM) Client VM
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]
EXTRA RELEVANT SYSTEM CONFIGURATION :
Problem seems to occur only on Windows OS -- I cannot reproduce the problem on Solaris. Problem occurred with JRE1.6.0_07, and earlier 1.6 releases, as well as 1.6.0_10). Problem does not occur with Java 1.5 (maybe because tooltips are not shown for not-focussed applets in Java 1.5?)
I have produced the problem with Firefox 2.0.0.17 and Internet Explorer 6.0 SP1
A DESCRIPTION OF THE PROBLEM :
When an applet window has focus and is positioned over an underlying applet embedded in the web browser, moving the mouse over the not-focussed applet and displaying tooltips causes the not-focussed applet (web browser window) to come to the front, thus hiding the focussed applet window.
Problem only occurs on Windows OS -- I do not see the problem on Solaris.
This problem appears to be a regression in Java 1.6 from Bug 4148057 which was fixed in Java 1.5.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile test case program, and run in web browser with test case HTML, using Java 1.6 plugin.
There will be a JTable applet in the web browser, and a little popup window named W2 with a JButton in it. Position the W2 window over the JTable, and click the button a couple times (i.e., verify that the W2 window has focus and is in front of the JTable.
Now move the mouse over the JTable. Tooltips will display for the items in the JTable. When you move the mouse over an item where the tooltip extends beyond the bounds of the JTable, the Web browser window with the JTable in it will come to the front, hiding W2. (The tooltip for "Function1" in Col3 is very long, so it works -- also the tooltip for any other cell in the JTable will work if it extends beyond the bounds of the JTable.)
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
W2 should stay on top (visible over the Web browser window with the JTable no matter where you move the mouse over the JTable (so long as you don't click the mouse to change focus, of course).
ACTUAL -
When mouse moved over a table cell where the tooltip extends beyond the bounds of the table, the Web browser window comes to the top and W2 gets hidden.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error messages.
REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
No workaround.
Release Regression From : 5.0
The above release value was the last known release where this
bug was not reproducible. Since then there has been a regression.
Customer requested to add the following information
I've been doing more testing of this problem,
and I've noticed something *in addition to* what I
wrote in the CQ:
For the sample program, in the Bug Report, I wrote that if
the tooltip for a table cell extends beyond the
bounds of the table when the table is not the
focussed frame and it is behind the
little popup with the button which has focus, then
if you move the mouse over a cell in the table with a
tooltip that extends beyond the table frame, then
the table comes to the top even though the little
popup with the button has focus.
What I did not write in that the problem occurrs "in the
opposite direction", also: If the frame with the table has
focus and is in front, and if you move the mouse over the
button in the popup, if the button's tooltip extends beyond its
frame, then the button popup panel comes to the front even
though it does not have focus, too.
This is a kind of "nit", but I think it
points out that the problem is not only with
tooltips for widgets embedded in a frame that
is embedded in the web browser, but the problem occurs for
other windows associated with the browser session
also.
Customer has done further testing and has
submitted another test program
More "good" news....
I did even more testing, and it looks like the
problem has nothing at all to do with using a
web browser.
I modified my Example program to run from the command
line and reproduced the problem.
