Tomcat not recreating work directory after it is deleted

Problem Description:

There is a scenario that you might run into when you restart Tomcat on a system that has been running for months.  In this case, the restart was for the purpose of installing a Windows update.  Tomcat restart/jasperserver would not complete.  You would get an "HTTP Status 404 - Not Found" error if you try to log into jasperserver as http://localhost:8080/jasperserver-pro, for example.

You would find dozens of these warnings in the log.  Another clue is that if you deleted Tomcat/work directory, it would not recreate it.

Possible Solution:

In this specific case, three files were deleted by accident.  After restoring them from a back up, Tomcat starts again. [Windows installation]

/users/abc/.jrsks, jrsksp, jslic

Looking in hindsight, if you search the log again, you will find another error embedded in the avalanche of WARNINGs.
