Timothy Bish updated AMQ-4715:
------------------------------
Description:
Every time when i start connection and create session i can see “java.exe” (in
task manger) memory get increase by 1000 to 2000K that’s ok.
Now, when i closed connection and session expecting to memory go down by 1000
to 2000K but nothing happening.
Here is my sample code.
{code}
public static void main(String[] args) {
try {
ActiveMQConnectionFactory connectionFactory = new
ActiveMQConnectionFactory("tcp://localhost:61616");
Connection connection= connectionFactory.createConnection();
connection.start();
for(int i=0;i<40;i++) {
Session session= m_connection.createSession(false,
Session.CLIENT_ACKNOWLEDGE);
Destination queueDestination = session.createQueue("TestQueue");
MessageProducer producer = session.createProducer(queueDestination);
producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
TextMessage textMessage = session.createTextMessage();
textMessage.setText(“some text”);
String jmsCorrelationId= UUID.randomUUID().toString();
textMessage.setJMSCorrelationID(m_jmsCorrelationId);
producer.send(textMessage);
if (producer != null) {
producer.close();
producer=null;
}
if(m_session != null) {
session.close();
session=null;
}
} // end for loop
if (connection!=null) {
connection.close();
}
}
}
{code}
If you will execute this program three to four times you will see significant
memory get increase in task manger for “java.exe”.
Thing most bothering me is that… after executing this program all allocated
memory should get cleaned-up by GC but look like somehow it’s not happening.
No idea what am I doing wrong?
Please help me!
