Here is my code.
ConsoleReader console = new ConsoleReader();
Completer quit = new StringsCompleter("quit");
Completer subcommands = new ArgumentCompleter(new StringsCompleter("with-number"), new StringsCompleter("with-string"));
Completer add = new ArgumentCompleter(new StringsCompleter("add"), subcommands);
Completer delete = new ArgumentCompleter(new StringsCompleter("delete"), subcommands);
Completer operations = new ArgumentCompleter(add, delete);
Completer aggregated = new AggregateCompleter(new StringsCompleter("run"), quit, operations);
console.addCompleter(aggregated);
When I try to complete the command I get this error.
Exception in thread "main" java.lang.NullPointerException

Code expected behavior:
> run [TAB]
add delete
> run del[TAB]ete [TAB]
with-number with-string
How can I fix my code to achieve that kind of behavior?
PS
I use JLine 2.12.
