AvoidRethrowingException


AvoidRethrowingException
Catch blocks that merely rethrow a caught exception only add to code size and runtime complexity.
    
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                    
//CatchStatement[FormalParameter
 /VariableDeclaratorId/@Image = Block/BlockStatement/Statement
 /ThrowStatement/Expression/PrimaryExpression[count(PrimarySuffix)=0]/PrimaryPrefix/Name/@Image
 and count(Block/BlockStatement/Statement) =1]
 
            
  
		    
		    
	    
	    
        
        
        Example:
            
                      
  public class Foo {
   void bar() {
    try {
    // do something
    }  catch (SomeException se) {
       throw se;
    }
   }
  }
