jaxws stack tests / jaxws-ri / performance / cache or not JAX-WS proxy/port

Hi,

There are many questions about cache or not JAX-WS proxy/port and the conclusion seems to be :

- It's a best practice to reuse the same instance of a proxy/port instance in my application to call my operations.

- only restriction is when we need change request context.

Do you confirm use of this pattern and the minimum version of jaxws-ri to do this (version which threadsafe is supoorted so)?

Thanks
