Strange behaviour on filesystem access
--------------------------------------

                 Key: DAEMON-172
                 URL: https://issues.apache.org/jira/browse/DAEMON-172
             Project: Commons Daemon
          Issue Type: Bug
          Components: Jsvc
    Affects Versions: 1.0.2
         Environment: Ubuntu 10.04, Java 1.6.0_20, jsvc installed via Ubunt=
u/Debian-Package-Management (apt-get)
            Reporter: Daniel Br=C3=B6king


Hi,

we are developing a Java-based application which does some filesystem opera=
tions on mounted USB-Storages.
While running it as a daemon via jsvc, the application is not able to acces=
s the mounted USB-Storage (e.g. on /mount/9201-9EFF).
[Misbehaviour: An empty file-list is gained while accessing the mount-point=
 via java.io.File.list()]

The storage has only the rwx-Permissions for a specific user:
>> $ ls -l /media/
>> drwx------ 10 daende daende 4096 1970-01-01 01:00 9201-9EFF

[!!!] The strange behaviour is that if the application is executed as root =
via a plain java-call, it gets access to the USB-Storage and is able to lis=
t the files located on the USB-device.

The jsvc is executed as root and is configured in the following way:
jsvc -debug -outfile "..." -errfile "..." -pidfile /tmp/$NAME.pid -cp "$CLA=
SSPATH" com.app.Main
