Re: java.lang.OutOfMemoryError (Almost SOLVED)

Finally...
After a LOT of try-and-fail, I found something which now is so obvious 
(eventhough it was not, at least for me... this only reveals how blind 
can someone be): the objects you want to survive after the 
AutoRelasePool is released have to be retained ---eventhough you own 
them?---.
The final code look like (it is inside a huge loop):

pool = [NSAutoRealasePool new];
array = [self giveMeAHugeArrayOfEOs];
en = [array objectEnumerator];
int sum = 0;

while(eo = [en nextObject]) sum += [eo intValue];

theSum = [NSNumber numberWithInt:sum];
/*HERE COMES THE IMPORTANT PART:*/
[theSum retain];
[pool release];

[results addObject:theSum]; // at this point, theSum is still a vivid 
object ;^()

HOWEVER: I had not found a way to assign more than 64Mb (the default) 
to my JVM in a Cocoa/EO app. If some one find out, please let us know,

Yours,
Dino


Thanks to Chuck and Others who helped solve this.
