This bug is filed for tracking purpose. Redhat just released SP2 for their
RHEL 3.0 line of products. Unfortunately on x86_64, the NX bit is turned on
by default. This will cause Java crashes.
If you are running on RHEL3 SP2 ('cat /etc/*release' should say something like
"Taroon Update 2"), and having problems running java applications (e.g.
'java -version' will crash), please make sure to boot with kernel option
'noexec=off':
. log in as root
. edit /boot/grub/grub.conf
. add 'noexec=off' to all kernel option lines, e.g:
title Red Hat Enterprise Linux AS (2.4.21-15.ELsmp)
root (hd0,1)
kernel /boot/vmlinuz-2.4.21-15.ELsmp ro root=LABEL=/ noexec=off
initrd /boot/initrd-2.4.21-15.ELsmp.img
NX bit is supported in JDK 1.5-beta2 and 1.4.2_05, see bug 4936784.
