Claus created LOGBACK-1274:
------------------------------

             Summary: Logback swallows output from Exceptions overriding toString()
                 Key: LOGBACK-1274
                 URL: https://jira.qos.ch/browse/LOGBACK-1274
             Project: logback
          Issue Type: Bug
          Components: logback-classic
    Affects Versions: 1.2.1
         Environment: Windows, Java 8
            Reporter: Claus
            Assignee: Logback dev list
         Attachments: logback.xml, LoggerTest.java

When logging exceptions that overwrite toString() then logback ignores the output of it. For example: 
{code:java}
   class OverridingException extends Exception {
        @Override
        public String toString() {
            return super.toString() + " important additional information";
        }
    }{code}
When used with logback the following code   
{code:java}
 @Test
    public void testName() {
        org.slf4j.Logger logger = LoggerFactory.getLogger(LoggerTest.class);
        try {
            throw new OverridingException();
        } catch (Throwable t) {
            logger.error("", t);
        }
    }{code}
produces output without the string "important additional information"
