Vaadin 7 at Webcenter Portal 12C

Hi Everybody,
It is Vaadin 7.x a good option to develop Portlets for Oracle WebCenter Portal 12C (OWC)?
I am evaluating tools for an OWC project, and obviously Vaadin was the first choice to came to my mind, but haven’t found enought information about OWC support on Vaadin 7.
I will appreciate any help.

Thanks in advance.

Well community, it looks like the answer is not by default.
I am going to test other frameworks over the OWC portal.
