Ceki Gulcu commented on LBCLASSIC-46:

The 'x commons framed omitted' helps to significantly reduce the number of printed stack lines for nested exceptions.  However, I don't think the nested  ThrowableProxy structure you propose precludes the calculation of commons frames.

>          Issue Type: Improvement
>          Components: Other
>    Affects Versions: unspecified

>            Priority: Minor
> Instead of a String representation of the whole Throwable stack trace incl. cause ThrowableInformation should instead look like this:
> public class ThrowableInformation implements Serializable
> {
>   String throwableClassName;
>   String message;
>   StackTraceElement[] stackTrace;
>   ThrowableInformation cause;
> }
> I omitted get/set and private in this example.
> StackTraceElement is perfectly Serializable and did also receive a public c'tor in Java 5 so I guess that the current ThrowableInformation is more or less a relict of log4j which had to stay compatible with older Java versions.
> You could obviously keep the getThrowableStrRep() method for compatibility.
> This bug is somewhat related to LBCLASSIC-45 because I think that ThrowableInformation should also, as LoggingEvent, be just a dumb data container with no real logic.
> The logic to extract the relevant StackTraceElements should IMHO be moved either into Logger or into a static factory method of ThrowableInformation.
