"Stack Over Flow Exception"

Problem Scenario :

We have a J2EE application, which has a front end in Java Swing with
heavy graphics usage & managed by the weblogic server. There are
several application details in the Hash maps with nested hash maps,
stored in a file. When the client launches the application, the file is
downloaded via Java Web start & this file is used for reading the data
from the hash maps. These days we are facing the Stack Over Flow
Exception when the file is being read.

Can you suggest something in this regard?
