Hi Marcel,


that's a fair point. :-) How can we get rid of Alien in #recreateSpecialObjects? Would it be okay to move it into something like "Alien initialize"? Or should #recreateSpecialObjects provide hooks/arguments to keep control of this central array?

<http://www.hpi.de/>

The method comment states that external packages should use addGCRoot() instead. Why doesn't Alien do so?

Best,
Christoph

Hi Christoph.

> Duplication hurts :-)

Now think again about modularity and global state. ;-) Take the slot for "Alien" as an example, which I replaced in "FFI-Callbacks". Projects are free to switch between compatible classes as the VM will happily produce the new instances. While this may not be true for all slots in the special-objects array, it is still true for many of them. So, #recreateSpecialObjectsArray may be the actual issue here.

Best,
Marcel

Hi Marcel,


why do we need a redundant #initialize method for this? Wouldn't it have been enough to trigger #recreateSpecialObjectsArray in a postscript? Duplication hurts :-)


Best,

Christoph
