I like it! There is at least one thing that I learned, if you really want to learn something, go to the source (of knowledge). Let the ones who live it tell you the story, not the ones who learned it.
Somehow related, I was trying to clarify a few things related to how class loaders work, and how are related to security. I lost a couple of days reading lot’s of stupid documents which left more questions the answers, till I found one document and a email, which made it all clear. The best material is always hidden.
