Joerg Pacher commented on IO-420:
---------------------------------
Issue is solved when changing FileAlterationOberserver.checkAndNotify to:
if (rootFile.exists()) {
rootEntry.setExists(true);
checkAndNotify(rootEntry, rootEntry.getChildren(),
listFiles(rootFile));
} else if (rootEntry.isExists()) {
rootEntry.setExists(false);
checkAndNotify(rootEntry, rootEntry.getChildren(),
FileUtils.EMPTY_FILE_ARRAY);
} else {
// Didn't exist and still doesn't
}
> Detection of deleted directories fails if the directory does not exist when
> the observer is created.
