While investigating RT-27029 we at NetBeans downloaded http://download.oracle.com/otn-pub/java/javafx/2.2.4-b18/javafx_samples-2_2_4-windows.zip, unpacked it, adjusted it to supply the missing NB FX Platform (by copying a prepared private.properties file to Ensemble/nbproject/private), and called "ant" without any parameters from the command line in the project's dir. This led to successful creation of Ensemble/dist/bundles with all the expected artifacts, but with the wrong icons.

Our QA contact Stepan Zebra discovered that the icon files in Ensemble/package/windows, macox and linux are named Ensemble2.ico (icsn,...). We had to rename the icon files to Ensemble.ico (icsn,...), i.e., to remove the "2" from their names, and to rebuild again with "ant", to get a native bundle with the correct icons being actually used.
