PreserveStackTrace


PreserveStackTrace
Throwing a new exception from a catch block without passing the original exception into the
new Exception will cause the true stack trace to be lost, and can make it difficult to
debug effectively.
      
		
		
		    
		    
    		    
    		    
    		    

    		    This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.design.PreserveStackTrace
    		    
		    
	    
	    
        
        
        Example:
            
                    
    
public class Foo {
    void good() {
        try{
            Integer.parseInt("a");
        } catch(Exception e){
            throw new Exception(e);
        }
    }
    void bad() {
        try{
            Integer.parseInt("a");
        } catch(Exception e){
            throw new Exception(e.getMessage());
        }
    }
}
