@Deprecated
public static interface CommandLine.IExceptionHandler2<R>
```
Deprecated.
see CommandLine.execute(String...), CommandLine.IParameterExceptionHandler and CommandLine.IExecutionExceptionHandler

Classes implementing this interface know how to handle ParameterExceptions (usually from invalid user input) and ExecutionExceptions that occurred while executing the Runnable or Callable command.
Implementations of this interface can be passed to the CommandLine::parseWithHandlers method.
This interface replaces the CommandLine.IParseResultHandler interface.
