[jira] Commented: (AMQ-1594) Closing an ActiveMQ connection causes
1.5 JVM to crash
[ https://issues.apache.org/activemq/browse/AMQ-1594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46462#action_46462 ]
Bruce Snyder commented on AMQ-1594:
-----------------------------------
It looks like the JVM crashed trying to read an entry in a ZIP file. I'm not sure if it's an issue with the libzip.so in the JRE/JDK that you're using or a problem with the JAR file from which the class is being loaded. First, I'd try to install a new copy of the JRE/JDK (from a fresh download of it) to check that it's not the libzip.so. If the JVM still crashes, then I'd try grabbing a fresh copy of the ActiveMQ libraries. It's possible that something was damaged during a download.
FWIW, when I encounter oddities like this with JAR files, I tend to use the {{jar}} utility to get a table of contents on the JARs as a test of those JARs. Below is an example:
{code}
$ for i in `ls /path/to/location/of/jar/files/*.jar`; do echo $i; jar tvf $i; done
{code}

> When I call "closeConnection()" (see below) after establishing a new connection to activeMQ my JVM crashes (see jvm crash log attached):
> Here are the details:
> I open a connection to activemq in the following manner:
> {code}
> private Session _session;
> private Connection _connection;
> private String _jms_url;
> private boolean _is_durable_subscriber;
> private MessageWrapperIntf _msg_wrapper_intf;
> protected static Logger log = Log.getLogger(MessageManager.class);
> public void createConnection(String jms_url, MessageWrapperIntf intf, boolean is_durable_subscriber) throws Exception {
> _jms_url = jms_url;
> _is_durable_subscriber = is_durable_subscriber;
> _msg_wrapper_intf = intf;
>
> log.info("");
> log.info("");
> log.info("Creating Connection to: " + jms_url);
> log.info("");
> String user = ActiveMQConnection.DEFAULT_USER;
> String password = ActiveMQConnection.DEFAULT_PASSWORD;
> //jms_url = addJMSOptions(jms_url);
> ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, password, jms_url);
> connectionFactory.setDispatchAsync(true);
> connectionFactory.setUseAsyncSend(true);
>
> _connection = connectionFactory.createConnection();
> _connection.setExceptionListener(this);
> if (is_durable_subscriber)
> _connection.setClientID(_msg_wrapper_intf.getClass().getName());
>
> _connection.start();
> _session = _connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
> }
> and then I close the connection as following:
> public void closeConnection() throws Exception {
> if (_session != null)
> _session.close();
> if (_connection != null) {
> _connection.stop();
> _connection.close();
> }
> }
> {code}
