Native libraries not found when using IBM JDK

The native components are not found on x86_64 using the IBM JDK because the startup script is looking in "lib" instead of "lib64".

You get this error:

2011-01-04 16:39:37,205 INFO [org.apache.catalina.core.AprLifecycleListener] (main) The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /home/mmillson/jboss/eap-5.1.0/jboss-as/native/lib

run.sh and run.bat set the native directory based on whether the reported version includes the string "64-bit":

IS_64_BIT_JVM=`"$JAVA" $JAVA_OPTS -version 2>&1 | $GREP -i 64-bit`
if [ "x$IS_64_BIT_JVM" != "x" ]; then
JBOSS_NATIVE_DIR="$JBOSS_NATIVE_DIR/lib64"
else
JBOSS_NATIVE_DIR="$JBOSS_NATIVE_DIR/lib"
fi

But with the IBM JDK "java -version" does not report that string:
