[TIMOB-575] Ti.UI.createToolbar crashes Android

The following app.js causes Android emulator to crash. It seems that Ti.UI.createToolbar has not been implemented?

[TRACE] E/TiModule( 274): (kroll$1) [8,401] Error creating proxy ti.modules.titanium.ui.ToolbarProxy: ti.modules.titanium.ui.ToolbarProxy [TRACE] E/TiModule( 274): java.lang.ClassNotFoundException: ti.modules.titanium.ui.ToolbarProxy

var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});

var mybtn = Titanium.UI.createButton({
    title:'Test',
    height:10,
    width:55
});

var toolbar2=Titanium.UI.createToolbar({
    items:[mybtn],
    bottom:0,
    borderTop:true,
    borderBottom:true,
    barColor:'#000'
});


win1.add(toolbar2);
win1.open();
