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<String,String> env = new Hashtable<String,String>();
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 !
