GWT Compilation Error while Parsing XML in JAVA

While running a Google Web Toolkit App I am getting this error during compilation. I have corrected the path of external Jars but no gain.Please help me what is the cause of problem (Unexpected error while processing XML) as I am unable to run this application is Super dev Mode. Thank you.

            [ERROR] Line 16: Unexpected exception while processing element 'inherits'

You have this line in your module .xml file:

 <define-property name="gwt.logging.popupHandler" values="ENABLED, DISABLED"/>

You also have the same line in one of the inherited modules. This leads to this error. Make sure you only have it in one place.
