This was a really great presentation. Thank you a lot for it.

I have only one remark about minute 24:30:

You say that it was Joshua Bloch or Gilad Bracha that published a paper
about the brokenness of Java classes. While both of them have numerous
contributions to the Java platform I think the paper you mean is:

Vijay Sarswat: Java is not type-safe.

The article is available here: http://www.cis.upenn.edu/~bcpierce/courses/629/papers/Saraswat-javabug.html

This is an older paper by Vijay and he has not put it on his site, I will write to him about this.

I am mentioning this because researchers live and die by their publications and it just it

I am giving the abstract here:

Abstract:
A language is type-safe if the only operations that can be
performed on data in the language are those sanctioned by the type of
the data. Java is not type-safe, though it was intended to be. A Java
object may read and modify fields (and invoke methods) private to
another object. It may read and modify internal Java Virtual Machine
(JVM) data-structures. It may invoke operations not even defined for
that object, causing completely unpredictable results, including JVM
crashes (core dumps). Thus Java security, which depends strongly on
type-safety, is completely compromised.

should be written as
Thread.sleep(3000);since sleep is a static method
