+## How to throw an exception in Groot Stream Platform
+When throwing an exception with a hint message and ensure that the exception has a smaller scope. You can create a custom exception class that include error code and message parameter in its constructor. For example, if you encounters a checked exception `ClassNotFoundException` while dynamic class loading，a reasonable approach would be to the following:
+ 
+```java
+   try {
+       // Class.forname
+   } catch (ClassNotFoundException e) {
+       throw GrootStreamBootstrapException("Missing class or incorrect classpath", e);
+   }
+   ```
