There has been much discussion and debate about new features for Java, such as the various closures proposals. Instead of talking about specific new features for the Java language, I'd like to take a step back and survey what the problems really are with Java right now. There's an old saying, "If it ain't broke, don't fix it," so I'd like to simply ask what's broke with Java right now?

Please post your list of Java pain points in the discussion forum. To keep weed out minutia (Java pin pricks), such as there's in the dictionary Cloneable wouldn't have an e, try and limit yourself to your top three pain points, in reverse order. Your most painful point will be your number 1, second most painful number 2, and third most painful number 3. Lastly, for each pain point, please try and explain the real business cost of the problem.
