* 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()).
