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

             Summary: Regression in ProviderUtil.hasProviders for 2.9.0
                 Key: LOG4J2-2033
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2033
             Project: Log4j 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.9.0
            Reporter: Andre Burgoyne


With release of 2.9.0, log4j no longer finds it configuration when running in an ant task.

{code:java}
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.util.ProviderUtil;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.Task;

public class AntTest extends Task {
    private static void logTest() {
        System.out.println("ProviderUtil.hasProviders() = " + ProviderUtil.hasProviders());
        System.out.println("LogManager.getContext() = " + LogManager.getContext());
        LogManager.getLogger(AntTest.class).warn("test warn");
    }

    public void execute() throws BuildException {
        logTest();
    }
}
{code}

This code when run with a log4j2.properties in the class path works fine with version 2.8.2, but when linked with 2.9.0 it fails:
