Re: Headless Cocoa/Java app - autorelease - solution ?


More vague docs on OSX/Cocoa/Java - NSPureApplication

<x-tad-bigger>public class Foo() extends NSPureApplication {


private doStuff(){
NSImage image = new NSImage(new URL("http://someplace..."));
// do stuff w/image.
return;
}

public static void main(String[] args){
NSApplication app = NSApplication.sharedApplication();
NSWindow dummy = new NSWindow();
NSGraphicsContext.currentContext().setImageInterpolation(NSGraphicsContext.ImageInterpolationHigh);
for(cnt = 0;cnt < 10; ++cnt){
doStuff();
}
Object o = new Object();
o.toString(); // place to set a breakpoint ;)
}
}

Using NSPureApplication, I get a large number of :
</x-tad-bigger><x-tad-bigger>2005-05-03 08:34:00.847 java[11408] *** _NSAutoreleaseNoPool(): Object 0x35f370 of class NSImageCacheView autoreleased with no pool in place - just leaking </x-tad-bigger><x-tad-bigger>

(2 per image instance to be exact) when the NSImage instance goes out of scope.

However, it seems that all the memory is reclaimed upon GC. Using the ActivityMonitor.app, I see both real and virtual memory end up ~where they started before entering the loop. Whereas not subclassing NSPureApplication, both the Real and virtual memory usage would just keep climbing until my system was choked.

So, while things *seem* to be working properly, I'm pretty spooked by the 'just leaking' messages.
Is there anyone from Apple listening ? Shed some light ?

Thanks.
