Description copied from class: SlaveRestarter

If SlaveRestarter.canWork() method returns true, this method is called later when the connection is lost to restart the agent.

Note that by the time this method is called, classloader is no longer capable of loading any additional classes. Therefore SlaveRestarter.canWork() method must have exercised enough of the actual restart process so that this call can proceed without trying to load additional classes nor resources.

This method is not expected to return, and the JVM should terminate before this call returns. If the method returns normally, the agent will move on to the reconnection without restart. If an exception is thrown, it is reported as an error and then the agent will move on to the reconnection without restart.

Specified by:

restart in class SlaveRestarter

Throws:

Exception
