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"
{code:java}
