Hi
Thanks; but i'm not shure if this is the problem,
for me just not clear why then the procfs must be enabled ?
this is the hint in build of openjdk6
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=

This OpenJDK implementation requires fdescfs(5) mounted on /dev/fd and
procfs(5) mounted on /proc.
If you have not done it yet, please do the following:
mount -t fdescfs fdesc /dev/fd
mount -t procfs proc /proc
To make it permanent, you need the following lines in /etc/fstab:
fdesc /dev/fd fdescfs rw 0 0
proc /proc procfs rw 0 0

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
i enabled it for jails
jail_jboss6_fdescfs_enable=3D"YES" # mount fdescfs in the =
jail
jail_jboss6_procfs_enable=3D"YES" # mount procfs in jail
and it will be mounted as this
devfs 1.0K 1.0K =
0B 100% /usr/jails/jboss6/dev
fdescfs 1.0K 1.0K =
0B 100% /usr/jails/jboss6/dev/fd
procfs 4.0K 4.0K =
0B 100% /usr/jails/jboss6/proc
=3D> not nullfs ? or do i understand something wrong ?
