A bug in Image class for S60

[cryptoalex]

Hello to all!

There is a BIG bug in series60 Java.

Just try to load some image in cycle.

boolean stop = false;
Image im = null;
int counter = 0;

try
{
   while(!stop)
   {
       im = Image.createImage("/someimage.png");

       counter++;    
   }
}
catch(IOExeption ex)
{

}

IOException is always thrown.
Value of counter depends on size of your image.
Bigger image size - exception is thrown earlier.

If image is about 2 KB, counter = 20,
if image = 10KB, counter = 4.

Nokia, I can send a test program to you

Looks more like a problem with the garbage collector not catching up with all the "garbage" (discarded images) your are leaving around there. You must be running out of memory pretty quick.

Hello to you! Thanks for the reply.

Yes, maybe this fact is correlated with OutOfMemory problem.
But:

1. Why IOException is thrown (why not OutOfMemoryError like it often happens on 7210 for example)?

2. How to deal with this GC bug, if images are big enough that i cannot hold them all in memory simultaneously, i.e. i need to delete old image objects and create new ones?

It is very pity that this problem happens on series60 phones, when they have pretty big memory, if comparing to series40.
I think Nokia should do smth with s60 GC...

Thanks for any help!
