[kaffe] Bug in garbage collector

[Guilhem Lavaux]

Hi pancake,

What version of kaffe are you using ? CVS ? I am getting a right OOM 
error when trying to call System.out.println. This is "normal" because 
the object o may not yet be relaxed even if you put 'o = null'. What 
sort of assertion failure do you get ?

I would expect something thrown by the just-in-time because it is still 
not completely rock solid relative to OOM.

Regards,

Guilhem.
