AppClient doesn't show directories in working directory

1. Create a job with Generic grid bean, application Hello and file set:
Path: C:\GPE4GTK\gpe4gtk1\tests\sources
Includes: javasources/*
2. Add output files: name is R, Value is *.
3. Submit job and then click Fetch outcome when job finished.
4. Tab Manage Output Files contained only 2 files
: .gpe_exit_status and .gpe_job_script.
But working directory contains the subdirectory jabasources with .java files. They aren't showed...
