[#8061] - Jaspersoft Studio broken in Eclipse Neon

Several problems in Eclipse Neon with 6.3.0. They might all be caused by a single exception:

Problems:
- "Palette" is empty in the "Report Design" perspective. Message: "A palette is not available"
- "Save" button doesn't become enabled when changing the report
- "Properties" view just shows the properties of the file, not of the selected report element.
- In the "Java" perspective, I get a "Palette" inside of the main editor. When I open a "Palette" using the menu Window -> Show View -> Other... -> Palette, it's empty again.
