FileWatcher.java does not recognize restored files

FileWatcher.java

Method:

public boolean isModified() {
long now = System.currentTimeMillis();
if((now - lastCheck) > 1000)

return stale;
}

A file is recognized as modified if the last modified timestamp is newer as the last known timestamp. In case of restoring a file with a backup/restore utility, the timestamp could be older. Replacing > with != gives

stale = file.exists() && (file.lastModified() != lastModified);

This will do the job.
