bounce

public void bounce()

Synchronously bounces (mean kills and restarts) this VM. Concurrent bounce attempts are synchronized but attempts to invoke methods on a bouncing VM will cause test failure. Tests using bounce should be placed at the end of the dunit test suite, since an exception here will cause all tests using the unsuccessfully bounced VM to fail. This method is currently not supported by the standalone dunit runner.

Throws:

RMIException - if an exception occurs while bouncing this VM, for example a HydraTimeoutException if the VM fails to stop.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getCurrentVMNum

public static int getCurrentVMNum()

getWorkingDirectory

public java.io.File getWorkingDirectory()
