Log4j2 и InstanceAlreadyExistsException, при создании Logger

Question

я переехал из log4j в log4j2 и увидеть следующий стек исключений,
при вызове:

private static final Logger LOG = LoggerFactory.getLogger(com.mine.pto.ejb_access.MyClass.class);

Исключение брошено иногда, при использовании нескольких потоков внутри applicaiton.

Любая идея, что я делаю неправильно с Log4j2?

Это может быть дубликат https://issues.apache.org/jira/browse/LOG4J2-1094.

Если это так, исправить - позвонить LoggerFactory.getLogger() перед началом любых тем.
