1 Allocate large numbers of huge BigIntegers in rapid succession. Most of the 2 associated memory will be in the C++ heap. This makes sure that we trigger 3 the garbage collector often enough to prevent us from running out of memory. 4 5 The test allocates roughly 10GB of native memory, approximately 1MB of which 6 will be live at any point. Basically all native memory deallocation is 7 triggered by Java garbage collection. 8 9 This test is a lot nastier than it looks. In particular, failure on target tends 10 to exhaust device memory, and kill off all processes on the device, including the 11 adb daemon :-( . 12
