Is +[NSMutableArray initialize] completely implemented?

[Philip Mötteli]

Hi


I'm trying to track down a strange exception, that I never had before 
the last CVS update:

: Uncaught exception NSGenericException, reason: subclass 
NSMutableArray(instance) should override initWithCapacity:


The backtrace, that leads to that is the following:

+[NSException raise:format:arguments:]
+[NSException raise:format:]
-[NSObject(GSCategories) subclassResponsibility:]
-[NSMutableArray initWithCapacity:]
-[NSMutableArray initWithObjects:count:]
-[NSArray init]
-[EDStack init]
+[EDStack stack]


So all happens during a very early phase of the program. Most classes 
haven't been called once yet.
I'm not sure, but I have the impression, that the problem could perhaps 
be situated here:


@implementation NSMutableArray

+ (void) initialize
{
  if (self == [NSMutableArray class])
    {
    }
}

+ (id) allocWithZone: (NSZone*)z
{
  if (self == NSMutableArrayClass)
    {
      return NSAllocateObject(GSMutableArrayClass, 0, z);
    }
  else
    {
      return NSAllocateObject(self, 0, z);
    }
}
...


Shouldn't there be some more code in + initialize? Because in the 
debugger the variable NSMutableArrayClass is been shown as having the 
value nil.
Probably, the problem is because +[NSArray initialize] has not yet been 
called, is it? There should be a mechanisme, that assures that or that 
initializes the same data.
