BrokenNullCheck
The null check is broken since it will throw a NullPointerException itself.
It is likely that you used || instead of && or vice versa.
     

		
		
		    
		    
    		    
    		    
    		    

    		    
This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.basic.BrokenNullCheck
    		    
		    
	    
	    
        
        
        
Example:
            
    
                

class Foo {
 String bar(String string) {
  // should be &&
  if (string!=null || !string.equals(""))
    return string;
  // should be ||
  if (string==null && string.equals(""))
    return string;
 }
}
