Unrelated ClassNotFoundException seen when starting an application

Troubleshooting


Problem

You notice there is a ClassNotFoundException displayed when starting an application that is not yet completely deployed.

Symptom

This problem can occur with different products that are installed and started automatically by 3rd party tools. One such case was with TFIM product where they installed their runtime component/application and it was started automatically using their script. The TFIM script asynchronously kicks off the start of the application prematurely while the application being deployed is not completely installed. The problem does not occur if the script waited a minute before starting the application.

In the above case the following errors are seen:

va:632)

Cause

Premature start of the application before it is completely finished with the installation. This is a timing issue between deploy of the application and starting of the application.

Resolving The Problem

Do not start the application until it has been completely installed.
