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

I see a memory leak in the Java broker when I try to use large number of connections in a loop even I close them properly at the end.

This issue can be recreated by running the following simple piece of JMS client code.

<snippet>
Properties properties = new Properties();
            properties.put("connectionfactory.qpidConnectionfactory",
                    "amqp://admin:admin@clientID/test?brokerlist='tcp://localhost:5672'");
            properties.put("queue.queueName", "example.RequestQueue");
            properties.put("java.naming.factory.initial", "org.apache.qpid.jndi.PropertiesFileInitialContextFactory");
            final Context context = new InitialContext(properties);

            for (int i = 0; i < 50; i++) {
                ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("qpidConnectionfactory");
                Connection connection = connectionFactory.createConnection();

                connection.start();
                connection.stop();
                connection.close();
            }
</snippet>

I can only use up to 1993 connections as JVM dies with an out-of-memory error at which point the JVM memory consumption is around 1G.
