Comment (by karsten):

 Second bug report: I believe that we're disregarding
 `StandardOpenOption.CREATE_NEW` in `PersistenceUtils.storeToFileSystem()`
 since the switch to temporary files.  We're checking that the temporary
 file does not exist, writing to it, and later renaming to the original
 file, thus replacing it.  What we should really do, when storing a file
 with `StandardOpenOption.CREATE_NEW`, is check whether the file exists and
 return false.
