Steps to reproduce:

1. Have a Jenkins job that uses the FSSCM plugin to copy from the file system into the workspace.
2. Execute the job at least once.
3. Change the modifiers on one of the files in the origin location, e.g. change the x (executable) bit from off to on (e.g. chmod +x filename)
4. Re-execute the job.

Expected result:

1. The modifier bit changes also in the checked-out version of the respective file.

Actual result:

1. The modifier bit does not change.
