I've tested all your propositions and this is the result:
- ldd command with and without LD_ASSUME_KERNEL=2.x.x show me this library list:
[root]# ldd /opt/IBMJava2-131/jre/bin/exe/java
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x00c74000)
libnsl.so.1 => /lib/libnsl.so.1 (0x0293e000)
libdl.so.2 => /lib/libdl.so.2 (0x00b49000)
libc.so.6 => /lib/tls/libc.so.6 (0x009ea000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x009d2000)
- echo "0" >/proc/sys/kernel/exec-shield
echo "0" >/proc/sys/kernel/exec-shield-randomize
Don't change anything
- Finally when I ran directly the java.exe (without using the wrapper), I have this error:
[root]# /opt/IBMJava2-131/jre/bin/exe/java
Unable to find xhpi, path used libjava.so/libxhpi.so
Could not create the Java virtual machine.

In that case:
echo "0" >/proc/sys/kernel/exec-shield-randomize
perl -pi -e 's/PRELINK_OPTS=-mR/PRELINK_OPTS="-mR --no-exec-shield"/' \
/etc/sysconfig/prelink
touch /var/lib/misc/prelink.force
/etc/cron.daily/prelink
On prelinked system, turning off exec shield randomization will help
you only a little bit, you need to tell prelink to put libraries
at 0x40000000 .. 0x50000000 addresses.
/proc/sys/kernel/exec-shield shouldn't make a difference I think,
as the JDK certainly doesn't have PT_GNU_STACK program header entry.
