FileDataStore: garbage collection can delete files that are still needed

Key: JCR-2063
URL: https://issues.apache.org/jira/browse/JCR-2063
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Reporter: Thomas Mueller
Assignee: Thomas Mueller
It looks like the FileDataStore garbage collection (both regular scan and
persistence manager scan) can delete files that are still needed.
Currently it looks like the reason is the last access time resolution of the
operating system. This is 2 seconds for FAT and Mac OS X, NTFS 100 ns, and 1
second for other file systems. That means file that are scanned at the very
beginning are sometimes deleted, because they have a later last modified time
then when the scan was started.
