createImage(byte[],int,int) bug on Nokia 7650

[bachin]

I've found a problem after several (300+) calls to createImage(byte[],int,int) on 7650. The function can not create image
The test program works well on other phones, but halts on 7650... I can email my sources to developers, if they want.
Thanks and sorry for my poor English.

Hi bachin,
I suppose your code looked as following:
...
is = conn.openInputStream();
byte [] buffer = new byte[(int)conn.getLength()];
is.read(buffer);
is.close();
Image image = Image.createImage(buffer,0,buffer.lenght); ... and so on
...
it's ok but unfortunetaly doesn't work on N7650 appart from
N6310i

for N7650 the solution is:
....
is = conn.openInputStream();
byte [] buffer = new byte[(int)conn.getLength()];
/*****************************************************/

int readLength;
int startRead = 0;
int endRead = (int)conn.getLength();
do {
readLength = is.read(buffer,startRead,endRead);
startRead = readLength;
endRead = endRead - startRead;
}
while(endRead > 0);
/*********************************************************/
is.close();
Image image = Image.createImage(buffer,0,buffer.lenght);
...
surely it works on both phones. :-)

I hope it will help you,
regards,
Janek

No, I do not use connections.
My program used alot of images and I've stored them into resource.
On load I read this byte array without any calls to createImage.
When my program needs the particular image - it accesses to this byte array and gets the image from it. And it doesn't work after several calls.
Fortunately, now I can store all my images in memory in this particular program, so I'm not forced to call the createImage function again and again. My post is only a bugreport for developers. Anyway, thanks for your comment.

I know this is a post that is 2 years ago, but I believe many people are still working on 7650, can anyone verify that this is indeed a 7650 specific bug?
I know this is a bug scarcely encountered in most developers, but I need to call createImage(byte[], int, int) constantly in my game and it crashes the game with the same IllegalArgumentException!
As far as I know, Nokia did not verify it in any documents, correct me if I'm wrong.
