Why do we still get SWT Invalid thread access Exception on Mac with -XstartOnFirstThread VM option?

问题

I'm working on a context simulator named siafu, just the first step, try to build and run it on Mac OSX 10.6.8, but I'm confused that it fails to run with Exception:

***WARNING: Display must be created on main thread due to Cocoa restrictions.
Exception in thread "GUI thread" org.eclipse.swt.SWTException: Invalid thread access
    at org.eclipse.swt.SWT.error(Unknown Source)
    at org.eclipse.swt.SWT.error(Unknown Source)

    at de.nec.nle.siafu.graphics.GUI.run(Unknown Source)
    at java.lang.Thread.run(Thread.java:680)

The script to run is like this, can anyone kindly point out why do we have exception even though we have specify the -XstartOnFirstThread?

#!/bin/sh

if [ "$1" = "-h" ]; then echo "Syntax: $0 [SimulationJarFile]"; exit 1; fi
if [ -n "$1" ]; then SIMULATION="--simulation=$1"; fi

java -Xmx512m -XstartOnFirstThread -classpath \
