the class Runner method start.

public ProcessSnapshot start(ProcessConfiguration processConfiguration, ProcessDefinition processDefinition, Map<String, Object> input) throws Exception {
    statusCallback.onRunning(instanceId.getValue());
    log.debug("start ['{}'] -> running...", processConfiguration.entryPoint());
    Command cmd = CompilerUtils.compile(compiler, processConfiguration, processDefinition, processConfiguration.entryPoint());
    State state = new InMemoryState(cmd);
    // install the exception handler into the root frame
    // takes care of all unhandled errors bubbling up
    VMUtils.assertNearestRoot(state, state.getRootThreadId()).setExceptionHandler(new SaveLastErrorCommand());
    VM vm = createVM(processDefinition);
    // update the global variables using the input map by running a special command
    // TODO merge with the cfg's arguments
    vm.run(state, new UpdateLocalsCommand(input));
    // start the normal execution
    vm.start(state);
    log.debug("start ['{}'] -> done", processConfiguration.entryPoint());
    return ProcessSnapshot.builder().vmState(state).processDefinition(processDefinition).build();
}
