OS X JavaApplicationStub running issues

Message 1 in thread

My application crashes when trying to run it from a .app with OS X's
JavaApplicationStub (I use the JarBundler ANT task but get the same effect
when packaging with the Jar Bundler application that Apple supplies in
/Developer/Applications/Java Tools...). I packed jambi.jar, its native
libraries and all my other dependent libraries into a single jar package
which I then supply to this JarBundler ant task.

The ant build.xml snippet I use is here:
    <target name="unpacklib" depends="compile">
        <mkdir dir="${unpacklib}"/>
        <unjar dest="${unpacklib}"><fileset dir="${lib}"><filename
name="*.jar"/></fileset></unjar>
        <copy todir="${unpacklib}/"><fileset
dir="${env.QTJAMBI_PATH}/lib"><filename
name="**"/></fileset></copy>
        <copy todir="${unpacklib}"><fileset dir="${ env.NMICA_HOME}"><filename
name="*.jnilib"/></fileset></copy>
        <delete dir="${unpacklib}/META-INF" />
    </target>

    <target name="jambijar">
        <jar jarfile="${dist}/lib/${name.main}_withlibs.jar"
basedir="${unpacklib}" manifest="${manifest.file.main}" compress="false">
            <fileset dir="${resources}"/>
            <fileset dir="${unpacklib}" />
        </jar>
    </target>

    <target name="jambiapp">
        <mkdir dir="${dist}/app"/>

        <jarbundler dir="${dist}/app"
            name="mXplor"
            mainclass="uk.ac.sanger.motifxplorer.app.MXplor"
            jar="${dist}/lib/${name.main }_withlibs.jar"
            icon="images/icon.icns"
            vmoptions="-XstartOnFirstThread"
            jvmversion="1.6+">
            <documenttype name="XMS motif set"
                    extensions="xms"
                    role="Editor"/>
        </jarbundler>

        <mkdir dir="${dist}/app"/>

    </target>

The interesting thing is it works just fine when I call it in the usual way
( java -XstartOnFirstThread -jar mxplor_withlibs.jar ) but gives this error
message when I put the same -XstartOnFirstThread in vmoptions which should
get rid of this specific crash (and indeed if I don't include it when
running with java -jar I get that same crash)! If I don't include it in the
Info.plist when launching the .app the application sometimes opens up for a
bit and even works works normally, and then crashes with a different error
msg (I've attached that below too). I assume this is an issue that has to do
with JavaApplicationStub and QT? Any ideas?

I was so happy to see it running, that I didn't let it run long enough 
to crash. With a little bit of effort (e.g. waiting for 10 seconds), 
mine crashes too.

It turns out that the "-XstartOnFirstThread" VM option is not supported 
by the JavaApplicationStub, the application that goes into 
bundle/Contents/MacOS and is used to launch java apps ;-(

If you instead use:

       <key>StartOnMainThread</key>
       <true/>

I then launches fine.
