Ralph Goers commented on CONFIGURATION-379:
-------------------------------------------

First, this really isn't a problem with Commons Configuration so you should close this issue.

As to how to solve it, there are a number of ways depending on what you are trying to do. Since you are getting the file name from a system property It appears that you are only dealing with a single property file. The file should be read when CIMSystem.init is called, so I really don't know why the configure method is being called again in the execute method. 

OTOH, if it was intended that each execution should have its own properties configuration then system.getConfiguration should really return a new CIMConfiguration.

If you have further questions I would suggest posting on the dev list.

> In one of my projects, we are using commons-configuration to read properties file.  There are multiple threads that are trying to read property in this property file and many times fails giving following exception:
