6.7.2 Random NullPointerException when using external tasks

ManKev

Hi,

We have been experiencing random error when using external tasks in teamsite 6.7.2. These same tasks ran wihtout problems on 6.7.1. It is difficult to debug because it is random and difficult to reproduce. We are running 6.7.2 on Solaris 9.

There error is emmenating from an Interwoven class, and looks like the server cannot to authenticate the task.

I would be interested in knowing if anyone else has experienced such a problem. Here is the stack trace.
