Worth noting that Eclipse 4.6 (Neon) seems to work with all items that fail with 4.4.x/4.5.2 including JasperStudio Editor using GTK3. However, maven integration is broken in neon so I am still stuck. Hopefully comparision of the differences in swt-gtk from 4.5.2 to the current neon release will help in fixing for 4.5.2 as well.
