No access to Java accessors during script evaluation

[hinerm]

The automatic Java Bean conveniences actually make scripting in renjin unintuitive at first (for a Java developer), and even make some operations impossible (as far as I can tell).

For example, running the script:

"import(java.util.HashMap)\n"
"ageMap <- HashMap$new()\n"
"print(ageMap$getClass())";

Causes:
org.renjin.eval.EvalException: Instance of class java.util.HashMap has no member named 'getClass'

Which would be manageable, except if I try to avoid using the accessor:

"import(java.util.HashMap)\n"
"ageMap <- HashMap$new()\n"
"print(ageMap$class)";

I still get an EvalException, for "no member named class".

In other cases the automatic Bean parsing worked great. But given this, it seems like Renjin is over-aggressive in stripping away accessors.

Also, I suggest preserving both accessor and direct field members to the External_Ptrs - so code from Java will work regardless of which it was written to use.

Thanks for the feedback!
I think this is a fair point - and I don't think there's any reason why we couldn't expose both the getters/setters as well as the property syntax. ageMap$class should also work, so I'll take a look at that.

fantastic! Love the project by the way :) very easy to code against
