I think it's reasonable to assume that the cache will only be used in
new applications, so you don't need to support as many JDBC versions as
the driver itself.
Actually, do you really need to have a separate version for each JDBC
version? Wouldn't a wrapper written and compiled with JDBC4 work with
older JDKs as well, as long as the application doesn't use the JDBC4
features? I might be missing something, I don't fully understand how it
works in the core driver either.
Have you considered using java.lang.reflect.Proxy? It has some overhead,
but is it significant in modern JVMs?
