             Summary: FilesystemStorageStrategyImpl throws NoSuchFileException when listing files
                 Key: JCLOUDS-1137
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-1137
             Project: jclouds
          Issue Type: Bug
          Components: jclouds-core
    Affects Versions: 1.9.2
            Reporter: Francois Rigault


When listing files in a local blobstore, we are sometimes hitting the following exception:

java.nio.file.NoSuchFileException: /opt/data/./ggg/fff_local_db.db-wal

There is some kind of race condition when a file is being removed in the middle of a getBlob: to reproduce, one can put a breakpoint in FilesystemStorageStrategyImpl.java on the call to UserDefinedFileAttributeView.list, and remove the current file from the file system.

We are hitting this error multiple times a day and don't really know how to proceed. Ideally, we would expect getBlob to return null in this case, instead of throwing a NoSuchFileException.
