Random Authentication Failures when using AdminConnectionFactory

Question

Has anyone experienced this problem when using the AdminConnectionFactory to create a JMXConnector. I have a Sun ticket open on this issue, but wanted to see if anyone else had any suggestions. Ticket # is 72502922
Our application uses the Sun AdminConnectionFactory to obtain a JMXConnector object. The code is being executed in a loop at a regular frequency. There is no dynamic nature to the code. All the information required to open a connection using the AdminConnectionFactory comes from static property files. So there is no question of one call being any different than a second call.
Every so often the call to create a connection fails with the exception message:

The code to create a connection using the AdminConnectionFactory is straight forward:
     JMXConnector jmxc = null;
try {
AdminConnectionFactory acf = new AdminConnectionFactory();
acf.setProperty(AdminConnectionConfiguration.imqAddress, hostname + ":" + port);
jmxc = acf.createConnection(user, password);
} catch (JMSException jmse) {
message = logMsgPrefix + "Cannot create JMXConnector to JMS server [" + hostname + ":" + port + "] using username [" + user + "] and password [" + password + "]";
log.error(message);
throw new GenericJMXException(message, jmse);
} catch (JMException jme) {
message = logMsgPrefix + "Cannot create JMXConnector to JMS server [" + hostname + ":" + port + "] using username [" + user + "] and password [" + password + "]";
log.error(message);
throw new GenericJMXException(message, jme);
What is causing this connection creation to fail. The same application will work just fine a few minutes later.

Thank you for the response.
Bug 6906978 is a defect that shows itself under high concurrency situations. In our case, we have a single quart based timer that is being triggered every 2 minutes to open a JMX connector. So my guess is that bug 6906978 and the problem that we have been experiencing are two different things.
But I am willing to try out 4.4U1P1. Any idea where I can download it from?
