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

That should work, thanks for the fix.
By the way, you could also use Google collections Mutlimap api instead to 
bypass all that ugly synchronized code.

> When using proxies for properties, a memory leak occurs.
> The ConcurrentHashMap classesToGetAndSetters  doesn't have an eviction policy 
> and fills up with proxies who do not get 
> garbage collected.
> Build a page which uses proxies as properties, every time a new session is 
> initiated, a new proxy (a new proxy is a new class) of the same property is 
> created and added to the map.
> if the proxy is create by a remote jvm you also get a classloader leak.
