I recently learned how to read thread dumps, and when I tried to test my knowledge with a production problem, the customer sent me a thread dump with the following format:



I did not understand anything (where are the monitors? What is the memory address? Who is the current thread? and so on...), I am used to see something like this:



Was this generated from a specific application server's interface? Is there a way to diagnose the problem with the vague information from the first format ?

thanks in advance,
Marcelo

Weblogic tries to rename the thread, with relevant data, such as the state. Other than that, the rest of the stack trace should be exactly the same -- except the name of the thread changes.

So, are you saying that this is a 'thread dump' generated by weblogic that keep the information more 'simple'?

So, it's a matter of which JVM generated them, right?
I still believe that HotSpot, JRockit and IBM JVMs will produce different outputs/formats in their thread dumps, do you know the difference between them?

Thanks.
