--------------------------------

Hi Dan,
good catch, I had mistakenly associated weak reference with out of memory 
errors but now see that that is the domain of soft references.
I wonder about the strong reference though, my use case is quite specific, 
repeated calls to getPort rather than caching ports. I wonder are there cases 
like arbitrary routers where a hard reference to a multitude of JAXBContext 
could be a memory hog?
It was the specificity of my use case in the context of a generic framework  
that caused me to think of the WeakHashMap in the first place.

> performance of repeated calls to jaxws.Service.createPort is poor, jaxb 
> context is created every time
