Anyone there able to make it work on OS X? Your help will be much appreciated. 
I've tried HANA Studio bundled from SAP, vanilla Juno and Kepler installations with tools.hana.ondemand.com repos and cannot make the SAP GUI integration to work in any of them.
Every time I select option "Open with SAP GUI" I receive the empty tab and error message in log:
Unable to create class 'org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor' from bundle '1154'
Unhandled event loop exception
and so on.
I have to GUIs installed 7.20rev11 and 7.30.
