When I'm not specifying CLASSPATH parameter and the jars are linked in MANIFEST.MF, the application is not started with message "Segmentation fault (core dumped)".

build.xml: <attached>

App1.cfg:
app.mainjar=testFxAppWithUtil.jar
app.version=1.0
app.mainclass=testapp/App1
app.classpath=$PACKAGEDIR/Util.jar
app.preferences.id=testapp

Jars: <attached>

If I remove "app.classpath=...", the application starts to work perfectly without any classpath issues (for example, no ClassNotFoundException )

Workaround is to set CLASSPATH when bundling.
