Shutdown class

Random shutdown component that crashes the process using various methods.

The component is usually used for testing, but brave developers can try to use it in production to randomly crash microservices. It follows the concept of "Chaos Monkey" popularized by Netflix.

Configuration parameters

• mode: null - crash by NullPointer excepiton, zero - crash by dividing by zero, excetion = crash by unhandled exception, exit - exit the process
• min_timeout: minimum crash timeout in milliseconds (default: 5 mins)
• max_timeout: maximum crash timeout in milliseconds (default: 15 minutes)

Example

var shutdown = Shutdown();
shutdown.configure(ConfigParams.fromTuples([
    "mode": "exception"
]));
shutdown.shutdown();         // Result: Bang!!! the process crashes
