> 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.
