You are correct that the exam focuses on the understanding of the Java language / platform and not so much on general "how-to's". It's not a hard exam, and I really wouldn't think that it demonstrates more than a medium level of familiarity with the platform. I got it a couple of years ago as part of a standardized training package at a company I worked at. I had medium skill with the language already and didn't study very much. As I recall, most of the ?'s were on generics and class inheritance - not surprising given the OO focus of the language.
