Provide a generator for Java

[roamingthings]

I like the concept and robustness of Smithy. I also like the code that is generated by the existing generators. In contrast my experience with OpenAPI generators especially for Java has been not very positive.

I would be very happy if you provide a generator for Java.

I have good news! We are working on one. We are working diligently to open-source a new smithy-java generator in the coming months. Stay tuned.
