,ExecutionControl
public class RemoteExecutionControl extends DirectExecutionControl implements ExecutionControl
The remote agent runs in the execution process (separate from the main JShell process). This agent loads code over a socket from the main JShell process, executes the code, and other misc, Specialization ofDirectExecutionControl
which adds stop support controlled by an external process. Designed to work withJdiDefaultExecutionControl
