[Bundlers] default classpath recognition stopped working in Linux

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.
