| * VM Testbase keywords: [quick, jpda, jdi, feature_jdk6_jpda, vm6] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * This is stress test against method "VirtualMachine.instanceCounts()". |
| * Test scenario: |
| * - Repeat the following steps 3 times: |
| * - Debuggee VM: create the number of different objects to consume 30% of available memory |
| * - Debuggee VM: create new thread 'GCProvocateur' which will try to consume the rest of memory to provoke GC |
| * - Debugger VM: at the same time call VirtualMachine.instanceCounts(VirtualMachine.allClasses()) 10 times |
| * - Debuggee VM: stop 'GCProvocateur' thread |
| * Test is treated as passed if no any unexpected events was caught during test execution and debuggee VM doesn't crash. |
| * |
| * @library /vmTestbase |
