STDOUT EXCEPTION:java.lang.NullPointerException Why?

[rnicholson10]

Whenever I interact with my application via a browser I am getting the following message printed out many times:

2010-01-12 15:24:18,838 INFO  [STDOUT] (http-0.0.0.0-8080-5) EXCEPTION:java.lang.NullPointerException

The number of times it prints is not dependent on the the action I am doing. I do not print this myself, I'm guessing it prints from somewhere in JBoss?

There is no stack trace or any other identifying information. Note that my application runs perfectly, I just get tonnes of these log messages filling up my log file.

Any ideas? I'm completely lost on this one.

Did you set anything in server.xml?

[rnicholson10]

No I did not.

I'm using JBoss AS 5.1.0.GA, should I be asking this question in another forum?

[erasmomarciano]

What options are you using the starting jboss?

[rnicholson10]

Here are my java opts:

JAVA_OPTS="-Xms1024m -Xmx1024m -XX:MaxPermSize=256m -XX:+UseParallelGC -XX:+AggressiveOpts -XX:+UseFastAccessorMethods -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.port=3454

And I start JBoss using: /opt/jboss/bin/run.sh -c default -b 0.0.0.0

mmmmm

it seems ok!!!

Check the file /etc/hosts  for errors

[rnicholson10]

My /etc/hosts file is fine.

The interesting thing is that I have two applications which exhibit this issue.

The first one is a Seam Application (packaged in an EAR). The other a simple EAR file with a single servlet in the war file and an MDB in the jar.

I'm going to try the same setup on another app-server on a different physical machine and see if the same thing occurs.
