tikluganguly: I was just starting netbeans after a system shutdown

pcw: <Finish> action in the debugger to stop debugging session.

amanjpro@yahoo.com: just, compiling and running (BTW, i changed my current date)..

the last compiled was done when my date/time (year) was set to the 2010...

but, i corrected it to 2008, and recompiled the class.. the exception occured

dkelly: Started NB6.5M1 and exception occurred pretty much from start without any interaction on my part.

Comment 3 David Simonek 2008-11-21 15:58:22 UTC 
I think it's not JDK bug, it's our bug probably in StatusLine where we are passing Alpha outside 0..255 range.
Comment 4 David Simonek 2008-12-03 16:52:55 UTC 
hopefully fixed: #92253ba8fd4e

Comment 8 David Simonek 2009-02-09 13:41:31 UTC 
Color fading code was deleted as part of 156357, making this issue obsolete.

However, if anyone wants to put fading back, note that to get rid of bug in color fading code, you need to replace
following code:

int alpha = 256 * (int)(Math.max(0, t - startTime)) / 2000;

with:

int alpha = Math.min(255, Math.max(0, 256 * (int)(t - startTime) / 2000));
