This post was originally posted as a reply to this topic, but the error messages are different, so I split it off into a new topic.
This is a very curious issue because it appears that the server is attempting to read /dev/null, which is basically a trash can.  I am curious to know exactly what you are doing to get this error. 
What version of Weblogic are you running?  What version of Java?
Is this server a new install or has it been up and running for a while?
Have you successfully deployed applications to this server in the past?
How are you starting Weblogic (i.e. do you have custom start up scripts?)
Is this exception produced when starting Weblogic or when deploying an application?
If when deploying, have you successfully deployed this application in the past?
The more details you give us, the more help we can give you.
