|
|
* The idea behind this test is that an array container pointers
|
|
* to circular linked lists is created in nativeGC03.java.
|
|
* Once the linkedlists are all created, a native function is called
|
|
* that trashes all the linked list by setting the elements of the
|
|
* array to null. After creating the garbage, a callback function
|
|
* is invoked that refills the array with new linked lists.
|
|
* The is goes on 10 times. The test passes if no OutofMemory exception
|
|
* is thrown.
