Rule agent not detecting deleted files and removing packages
------------------------------------------------------------

                 Key: JBRULES-1660
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1660
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.7
            Reporter: Michael Neale
         Assigned To: Michael Neale
             Fix For: FUTURE


1) If I delete a file, it does not remove those rules from the rules base. I assume that this is because all we get back from a the FileScanner.getChangeSet() is a Package[], which is the list of packages to load. There is no code to indicate that it will do a File.exist() on the list of file handles in the scanner to see if any packages have disappeared.

2) In the case where I remove one .drl and create a new different one, (in addition to point 1, where the old one is not removed) the new one is also not picked up. The problem lies in an assumption in the DirectoryScanner.loadPackageChanges(). The following line

   if ( currentList.length != dir.listFiles().length ) {

assumes that if the number of files in the directory has not changed, then it really is the same list of files were dealing with. In my case this is not true, and hence it does not give the new list of files to the FileScanner to load.
