 * @summary converted from VM Testbase nsk/jvmti/DataDumpRequest/datadumpreq001.
 * VM Testbase keywords: [jpda, jvmti, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *     This test exercises the JVMTI event DataDumpRequest.
 *     It verifies that the event will be sent only during the live phase of
 *     VM execution.
 *     The test works as follows. The agent enables the DataDumpRequest
 *     event on 'OnLoad' phase. Then the java part run a special perl script
 *     'datadumpreq001.pl' in a separate child process. The script obtains PID
 *     of its parent process and sends it the signal QUIT (CTRL-\). If the
 *     DataDumpRequest was not send and/or the script failed, the test ignores
 *     it and passes. Otherwise, the VM phase is checked during the
 *     DataDumpRequest callback.
 * COMMENTS
 *     Note that obtained PID mentioned above may not belong to the java
 *     process itself in non-HotSpot VMs. It may happen if VM runs child
 *     process indirectly via a separate shell.
 *     Besides that, sending CTRL-\ causes the HotSpot VM itself to print its
 *     full thread dump. The dump may be ignored.
 *
 *     The test has been fixed due to the bug 4947594.
