[jira] [Created] (LOG4J2-2050) NullPointerException in
LogManager.getLogger when called from anonymous class initializer
Mark Arnold created LOG4J2-2050:
-----------------------------------
Summary: NullPointerException in LogManager.getLogger when called from anonymous class initializer
Key: LOG4J2-2050
URL: https://issues.apache.org/jira/browse/LOG4J2-2050
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.9.0
Reporter: Mark Arnold
Priority: Critical
I observed a NullPointerException when calling LogManager.getLogger in the initializer block of an anonymous class, like so:
{code:java}
SomeInterface _t = new SomeInterface() {
Logger log = LogManager.getLogger();
@Override
public String someMethod() {
log.info("Logging...");
return "";
}
};
{code}
This did work fine in 2.8.2, but 2.9.0 gets an NPE:
