I think this is a bug in ThrowableProxy. Could you please create a jira
issue for this? Thank you.

Hi Ceki,
Thanks for the response. Here's a trivial example:
public class Main {
public static void main( String[] args ) {
org.slf4j.Logger logger = org.slf4j.LoggerFactory
.getLogger( Main.class );
Exception e1 = new CustomException( );
e1.printStackTrace( System.out );
logger.info <http://logger.info>( "", e1 );
System.out.println( );
Exception e2 = new CustomException( "Test message" );
e2.printStackTrace( System.out );
logger.info <http://logger.info>( "", e2 );
}
static class CustomException extends Exception {
CustomException( ) {}
CustomException( String message ) { super( message ); }
@Override
public String toString( ) {
return super.toString( ) + " (from toString)";
}
}
}
Running the above yields this output:
com.example.logback.Main$CustomException (from toString)
at com.example.logback.Main.main(Main.java:7)
17:19:50.445 [main] INFO com.example.logback.Main -
com.example.logback.Main$CustomException: null
at com.example.logback.Main.main(Main.java:7) ~[classes/:na]
com.example.logback.Main$CustomException: Test message (from toString)
at com.example.logback.Main.main(Main.java:13)
17:19:50.451 [main] INFO com.example.logback.Main -
com.example.logback.Main$CustomException: Test message
at com.example.logback.Main.main(Main.java:13) ~[classes/:na]
What do you think?

Hi Abraham,
Can you provide an example of the difference?

Hi,
In comparing the outputs of Throwable#printStackTrace and logback, I
found an inconsistency in how the Throwable instances are
printed. While
the former delegates to the Throwable instance's #toString
method, the
latter (partially) re-implements the default implementation in
Throwable, which means that data contained in the #toString
methods of
Throwable subclasses is discarded. While this is easy to work
around in
my own code, there is still a problem when working with third-party
libraries.
Is there a configuration option that would allow me to specify
my own
IThrowableProxy implementation? (I couldn't find any pages
describing
the extension points and how to activate them.) Or would it be more
appropriate to modify the ThrowableProxyUtil class so that it
behaves
similarly to #printStackTrace? Any ideas would be greatly
appreciated.
Thanks in advance!
