Supporting into Own Space

[I_Nod_Well]

Hello, I have a rules resolution question.

What would happen if I supported myself into a space that I occupy while someone else also supports themselves into that space?

To illustrate:
France has armies in Burgundy, Paris and Marseilles.
Germany has armies in Munich and Ruhr.
France orders:
Burgundy to Munich
Marseilles to Burgundy
Paris support Marseilles to Burgundy
Germany orders:
Munich to Burgundy
Ruhr support Munich to Burgundy

Would it all bounce, or would Germany get into Burgundy because France is attacking their own unit?
Does it make a difference if Ruhr moves instead of Munich?

[Restitution]

They would bounce. All the units would stay where they are. It would not have mattered if Ruhr moved instead, because units cannot cut support being used to attack them.

Thanks for the answer!
