Subject [jira] Updated: (DERBY-4443) Wrap rollback in exception handlers in try-catch
Date Sun, 06 Mar 2011 05:35:45 GMT

Houx Zhang updated DERBY-4443:
------------------------------

    Attachment: DERBY-4443.patch

I think it's a good point for a new comer. I have providing a patch. In my patch, a method
named rollBackWhenSQLExceptionOccurs() is added. I'm not sure there is any other place to
use this function, if so, it's better to add this method in a independent util class.

Please check it and give some advice, thanks!

> Avoid this pattern everywhere:
> 		}catch(SQLException se){
> 			//issue a rollback on any errors
> 			conn.rollback();
> 			throw  se;
> 		}
> because an error in rollback will shadow the original exception.
