Install4j Not delete file

Question

I have such action before install files:

I want to delete all jar files in app (if such are available) As result jar files don't delete. In logs:

[INFO] com.install4j.runtime.beans.actions.files.DeleteFileAction [ID 270]: Execute action
       Property directoryFilter: null
       Property fileFilter: com.install4j.script.I4jScript_Internal_115
       Property files: [.]
       Property filesRoot: null
       Property backupForRollback: false
       Property recursive: false
       Property rollbackSupported: false
       Property showFileNames: true
       Property showProgress: false
       Execute action successful after 2 ms

P.S. Tested on Linux. Try to obtain max privileges is on for Linux build.
