Java 1.4.1 dumps core in _smalloc (SEGV) when trying to access nfsv2 mounted
directory via -Djava.endorsed.dirs=<nfsv2_mounted_dir>.

Problem is easily reproducible running through the following steps:

1. Setup
--------

Mount a directory, that is non-empty and has some non-trivial contents:

Mountpoint was chosen /mnt
% ls -al /mnt
total 4
drwxrwxr-x 2 root sys 512 Oct 12 1999 .
drwxr-xr-x 35 root root 1024 Nov 22 12:38 ..
%

Mount filesystem nfsv2
% su
Password:
# mount -o vers=2,ro lab153:/export/dist /mnt
#
# ls -al /mnt
total 194
drwxr-xr-x 12 root other 512 May 29 2001 .
drwxr-xr-x 35 root root 1024 Nov 22 12:38 ..
