-------------------------------

             Summary: Log4j 2 is not working with JDK 1.7
                 Key: LOG4J2-64
                 URL: https://issues.apache.org/jira/browse/LOG4J2-64
             Project: Log4j 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0-alpha1
         Environment: OS: Mac OS X and Linux CentOS 6.3

javac 1.7.0_05

Java(TM) SE Runtime Environment (build 1.7.0_05-b06)

            Reporter: Ivan Anev
             Fix For: 2.0-alpha1


Even a simple example as:

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Test {

    private static final Logger logger = LogManager.getLogger(Test.class.getName());

    public static void main(String[] args) {
        logger.error("Testing...");
    }

}

Results in:

Exception in thread "main" java.lang.VerifyError: class org.apache.logging.log4j.core.impl.ThrowableProxy
