Oh, I've seen it first hand, I use netbeans.

But I'm not sure it's due to the GC, and not due to it requiring 2x or  
more memory than an equivalent manually managed application requires.  I  
honestly don't konw.

Generally bad things happen when memory gets low, no matter what the  
memory management system or language.
