Sergey,
OK. You can file a request to improve TrayIcon test coverage but it's
an another story. Here we are discussing regression test for a
specific bug.
I cannot agree with the approach you've proposed. In your logic we
need start to write regression tests for all methods in JDK classes
those take String parameters by iterating all possible parameters
lengths to discover potential bugs.
Yes, if we know that there is a high probability to crash the method.
Tests need to be written by certain rules. Scanning all possible
values of input parameters is not the best rule in my opinion.
Validation of one number is useless too. Its even does not check all
corner cases , 0,1,max-1,max,max+1. so the range is better.

I think it's more like bug regression test policy. Since I'm a
novice in the project maybe you or somebody can advise me the right
process.
Lets see what we have here:
The fix is connected to the windows platform native code only. It is
a platform specific corner case. I would not say it contains "magic
numbers", those numbers a not magic for the native layer. But in the
test we call native code from java where in truth string parameters
maximum lengths are not specified.
I think it make sense to run the test on all other platforms test
iterating strings lengths up to 1000 or more just to ensure that
there no similar issues there. We can do this once or have an option
to switch this scenario on.
The goal of the test is to catch all possibly related issues. So
instead of numbers use ranges, cover all platforms if the test don't
use platform's specific classes, cover all look and feels, automatic
test is better than manual, make the test generic. But it has of
course some restrictions like performance and stability. Moreover it
seems that right now displayMessage/setToolTip are used in the manual
tests only.
But I'm not 100% sure that such test scenario should be included in
the regular regression run because sending messages to the system
tray is not very fast and the scan can take noticeable amount of
time. In my opinion such issue seeking scenario is reasonable to run
time to time or as a part of stress testing profile, but it does not
make sense to run it during the regular regression because it tests
nothing specific on platforms other than Windows and even in Windows
there is only one specific lengths combination. It's not worth to do
this potential issue seek it's time expensive but will not bring us
a lot of value really.

Hi, Semyon.
I suggest to remove stuff related to windows platform from the
test. Also it will be good to test some reasonable range of data
instead of magic constant, wrap setTooltip/displayMessage in a loop.
Please add "tray.remove(trayIcon);" at the end of the test,
otherwise it can hang, when will be run w/o jtreg.

Just few comments about the test:
- The test sets WindowsLookAndFeel and seems fails on non
Windows platforms.
- There is the second SystemTray.isSupported() check on line
49. Does it depends on L&F?
- The copyright should be updated to 2015.
Thanks,
Alexandr.
