Java just sucks
The Java rant...
Java fails in every aspect it was intended.
Jboss configuration is absurd.
I hate XML. Although this guy doesn't and has one of the few sensible articles defending it. While I disagree with many of his points at least he has solid points instead of the usual "everyone is using it so why argue even if it isn't good...".
Ant is completely retarded.
Java is actually harder to port than Python.
Java's Checked Exceptions completely miss the point of exception handling. Exception Handling as a concept isn't intended to force you to handle exceptions. Exception Handling was supposed to make exception handling easier; clear; and remove clutter from code. Checked Exceptions actually forces you to add clutter. C++ and Python do exception handling sooo much better.
