      Description

      I have running a blueprint file with a camel context that has the following:

               <from uri="file:///{{backupFolder}}?doneFileName=${file:name}.4camel&amp;recursive=true&amp;delete=true"/>
      

      This causes Camel to throw the following exception when I receive files with names of the following form: YY049608$SQLEXPRESS_TEST1_FULL_20170709_160016.bak

      Most likely the '$' in the name is the problem. Is there any way to escape it?
