| * Test checks work of Attach API (com.sun.tools.attach). |
| * Test is based on the nsk.share.aod framework. |
| * Test checks following methods: |
| * - VirtualMachine.getSystemProperties() (test checks that returned properties contains |
| * expected property and tested method returns properties whose key and value is a String) |
| * - VirtualMachine.getAgentProperties() (test checks that method returns properties whose |
| * key and value is a String) |
