/**
|
|
* This test exercises the JVMTI event <code>DataDumpRequest</code>.
|
|
* <br>It verifies that the event will be sent only during the live
|
|
* phase of VM execution.<p>
|
|
* The test works as follows. The agent enables the DataDumpRequest
|
|
* event on <code>OnLoad</code> phase. Then the java part
|
|
* imitates Ctrl-\ or Ctrl-Break (on Windows).If the DataDumpRequest
|
|
* was not send the test ignores it and passes. Otherwise, the VM phase
|
|
* is checked during the DataDumpRequest callback.<br>
|
|
* Note that sending CTRL-\ causes HotSpot VM itself to print its full
|
|
* thread dump. The dump may be ignored.
