I have a Windows XP and use jdk1.6.0_16 I want to know the work
around [for this] compiler warning:
"com.sun.image.codec.jpeg.JPEGCodec is a Sun
proprietary API and may be removed in [a future release]"
To show my efforts to find a solution I read Bug Database:
<http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6476630>
A final, late date, posting to this bugs request link says: "However,
in practice developers either maintain a zero warning count or they
ignore warnings. Those that maintain zero warnings will need to be
able to acknowledge the issue once and, if they gotta use the hidden
functionality, suppress the warning." I want to know what it means to
"maintain zero warning count". What do I write?
A "zero warning count" seems a bit Procrustean, but a "minimal warning
count" makes some sense. Fewer may be unrealistic; more means you may
miss new warnings as they arise.
In this particular case, it may mean you are using features of the code=
c
that aren't available through a published API, for example,
javax.imageio.ImageIO:
<http://java.sun.com/javase/6/docs/api/javax/imageio/ImageIO.html>
Using Sun proprietary code may also engender licensing problems.

Hi All,
Thanks for your responses.
Can I digress but not alter this thread of
my original post? Is JPEG the issue then what
image form is not an issue? Or is it not an issue,
but what is done to the image form namely
cutting a jpeg image into 16 images from the
original image. Or is it something entirely
different?
TIA
