unable to directly handle unknown commands in console

[aappddeevv]

There is no way to definitely say, other than parsing a string, whether a command was not recognized in jline.console.

UnknownCommandException is not public, hence, the best catch you can have is Exception. But then you have to check the string for "unknown" in it. It would be nice to have that public or have a method that helps you determine when a command was not recognized in the registry. Handling an unknown command is probably not a registry specific function but could be owned by the outer layer. To be consistent with parts of jline.console, perhaps the UnknowCommandException needs to be public.

SystemRegistryImpl can be used: 1) without scripting support and 2) with scripting support (using ConsoleEngine/ScriptEngine implementations). In a latter case UnknowCommandException will be handled internally in SystemRegistryImpl and it is never thrown outside.

When you use SystemRegistryImpl without scripting support you can test whether the command is known as

String line = reader.readLine("prompt> ");
if (systemRegistry.hasCommand(parser.getCommand(line))) {
    systemRegistry.execute(line);
}

where systemRegistry and parser are instances of SystemRegistryImpl and DefaultParser.
