Thanks for your fast reply.

sudo -K and sudo -K seems to work in command line but the EUID / UID of
a Java application do NOT fork().

After a call to gksudo using ProcessBuilder(), the WaitFor() mnthod
returns, then, another ProcessBuilder does bash -c '/usr/bin/gksudo -k'

The command works perfect but the next ProcessBuilder() is still
elevated so it doens't do anything.

The feature of gksudo is kool, another attempt to be "user friendly" but
in other situations we do need more control over run command as root or
run them as a normal user.

If a JVM is "elevated", the System.getProperty("user.home"); will return
root's home, bcause gksudo was ran 2 minutes ago.

Can anyone please help ?

thanks,
