Speed up check for modifications of tracked resources
We only need to check file existense if some other stat returns a value that may mean that the file does not exist. File.length() == 0 or File.lastModified() == 0 are two such properties. We use length here. Change-Id: If626b12e7bb4da994b5c086f6a5b7a12c187261c Signed-off-by: Robin Rosenberg <robin.rosenberg@dewire.com>
