Answer 1

Memory management

All about Java Virtual Machine , which is part of the OS:

The BlackBerry® Java® virtual machine manages memory usage on your BlackBerry device. The BlackBerry JVM allocates memory, collects garbage, and automatically changes data between SRAM and flash memory. The BlackBerry JVM must also provide available memory between the BlackBerry device application and the BlackBerry® Java application. Memory capabilities represent the total amount of available memory that is larger than the available working memory when all applications and related application data exist on BlackBerry.
