| * DESCRIPTION |
| * The test scenario is following: |
| * - Debugger VM |
| * - initiate creation a number of instances in debuggee VM using ClassType.newInstance |
| * - check the number of instances is correct |
| * - initiate creation a number of instances in debuggee VM using ArrayType.newInstance |
| * - check the number of instances is correct |
