Eric Milles commented on GROOVY-11230:
--------------------------------------
The article mentions resizing the map. In our case, we guaranteed the capacity
at creation time and cap the size.
> ProxyGenerator creates a lot of AtomicReference instances regardless of
> "groovy.adapter.cache.default.size" setting
