Just thinking out loud here...
Though documented, people really seem to have issues with
- heap memory sizes, live vs dead objects, allocated / free /used memory, ...
- shallow / retained sizes
- Java memory vs OS memory
...
I'd guess most people without C/C++ experience get bitten by this.
Maybe people would appreciate a little article, where you show how things work, maybe by walking through a simple example, and a few pointers to relevant OS and Java memory articles (eg http://java.sun.com/developer/technical ... LT/RefObj/)
