| * VM Testbase keywords: [feature_282, jdk] |
| * VM Testbase readme: |
| * Description : |
| * Test checks work of Attach API (com.sun.tools.attach). |
| * Test is based on the nsk.share.aod framework. |
| * This test tries to attach to the VM started by this test using 2 methods: |
| * - AttachProvider.attachVirtualMachine(String id) |
| * - AttachProvider.attachVirtualMachine(VirtualMachineDescriptor vmd) |
| * After attaching test tries to use created VirtualMachine object (tries to call VirtualMachine.getSystemProperties()). |
| * |
