Hi,
Here's an update, as identified by a work colleague...
After sending the message there was no tidy up code (e.g. call to 
connection.close(), etc.).
The issue could be reproduced when both systems were up and running and then 
doing a reboot on the remote host.
 All is well now (after applying the fix).
Many thanks Ed !

Hi,

Our system works fine but after a period of time (e.g. a few days) we are 
getting a java.lang.NullPointerException on calling 
factory.createQueueConnection.

Here is an extract of the code:
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
env.put("java.naming.provider.url",aHost+":1099");
InitialContext ctx = new InitialContext(env);
QueueConnectionFactory factory = (QueueConnectionFactory) 
ctx.lookup("ConnectionFactory");
connection = factory.createQueueConnection();

The stack trace is at the bottom.

One thing we've noticed is that in wrapper.log on the server we are sending the 
message to, around the same time of the NullPointerException, the following is 
logged:
WARN   | wrapper  | 2012/11/01 10:01:34 |

Any thoughts on why it's crashing on calling factory.createQueueConnection and 
why the JVM is restarting on the remote host ?

Note that both systems are on Windows and have the following setting in 
service.bat:
set JAVA_OPTS=-Xrs

Thanks !
