Review request for sentry, Alexander Kolbasov, Arjun Mishra, kalyan kumar
kalvagadda, Na Li, and Sergio Pena.
Changes
-------
Fixed the path of SentryMain.java
Repository: sentry
Description
-------
TheSentryMain class currently works by mapping the command name to a Java class
that is then dynamically loaded:
String commandName = commandLine.getOptionValue(COMMAND);
String commandClazz = COMMANDS.get(commandName);
Object command;
try {
command = Class.forName(commandClazz.trim()).newInstance();
} catch (Exception e) {
String msg = "Could not create instance of " + commandClazz + " for
command " + commandName;
throw new IllegalStateException(msg, e);
}
if (!(command instanceof Command)) {
String msg = "Command " + command.getClass().getName() + " is not an
instance of "
+ Command.class.getName();
throw new IllegalStateException(msg);
}
((Command)command).run(commandLine.getArgs());
}
This ia too complicated and causes subtle problems at runtime. Instead it
should just create a new instance of appropriate class and call it directly.
