CODSTA.NCE

Never use `Exception', RuntimeException', or `Throwable' in "catch" statement

Description

This rule flags code that tries to "catch" an `Exception', `RuntimeException', or `Throwable'.

`Exception', `RuntimeException', and `Throwable' are too general.

Example

 package CODSTA;
 
 public class NCE {
     void method () {
         try {
         } catch (Exception e1) {
         }
         try {
         } catch (RuntimeException e2) {
         }
         try {
         } catch (RuntimeException e3) {
         }
     }
 }

Repair

Deal with subclasses of `Exception', `RuntimeException', and `Throwable' when handling exceptions.
