EmptyCatchBlock


EmptyCatchBlock
Empty Catch Block finds instances where an exception is caught,
but nothing is done.  In most circumstances, this swallows an exception
which should either be acted on or reported.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
        
//CatchStatement
 [count(Block/BlockStatement) = 0 and ($allowCommentedBlocks != 'true' or Block/@containsComment = 'false')]
 [FormalParameter/Type/ReferenceType
   /ClassOrInterfaceType[@Image != 'InterruptedException' and @Image != 'CloneNotSupportedException']
 ]
 
             
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public void doSomething() {
  try {
    FileInputStream fis = new FileInputStream("/tmp/bugger");
  } catch (IOException ioe) {
      // not good
  }
}
 
      
            
  
        

        
        
            
                This rule has the following properties:
                Name Default value Description
                
                
                    

                    allowCommentedBlocks
                    
                    Empty blocks containing comments will be skipped
