Description

I'm investigating switching to Artemis.  I created a simple embedded broker and a VM connection to it.  After completion, the VM hangs for 1 minute on exit.

The following is the simple code:

EmbeddedActiveMQ server = new EmbeddedActiveMQ();
server.setConfigResourcePath(xml);
server.start();
TransportConfiguration transportConfiguration = new TransportConfiguration(InVMConnectorFactory.class.getName());
ConnectionFactory cf = ActiveMQJMSClient.createConnectionFactoryWithoutHA(JMSFactoryType.CF, transportConfiguration);
Connection connection = cf.createConnection();
connection.close();
server.stop();

The configuration:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<configuration xmlns="urn:activemq" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:activemq /tmp/artemis-configuration.xsd">
   <core xmlns="urn:activemq:core">
      <persistence-enabled>false</persistence-enabled>
      <security-enabled>false</security-enabled>
      <journal-type>NIO</journal-type>
      <journal-pool-files>1</journal-pool-files>
      <acceptors>
         <acceptor name="in-vm">vm://localhost</acceptor>
      </acceptors>
   </core>
</configuration>

I have attached the log.

Also, does anybody know why there is so much logging at INFO?
