Description:

With a default logback.xml containing this
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<contextName>Foo</contextName>
[..]
</configuration>
reloading the Logback configuration by means of
private static void initLogbackConfig(URL configUrl) {
ILoggerFactory loggerFactory = LoggerFactory.getILoggerFactory();
if(loggerFactory instanceof LoggerContext) {
LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory();
// reset previous configuration initially loaded from logback.xml
loggerContext.reset();
JoranConfigurator configurator = new JoranConfigurator();
configurator.setContext(loggerContext);
try {
configurator.doConfigure(configUrl);
StatusPrinter.print(loggerContext);
} catch(JoranException ex) {
StatusPrinter.print(loggerContext);
}
}
}
with a file containing
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<contextName>Foobar</contextName>
[..]
</configuration>
produces the following error:
12:21:28,919 |-ERROR in ch.qos.logback.classic.joran.action.ContextNameAction - Failed to rename context [Foo] as [Foobar] java.lang.IllegalStateException: Context has been already given a name

Is this expected behavior? After all, loggerContext.reset() has been called and I'd assume that this would also reset the contextName. Feels like a bug.
