What's the most frustrating thing about JAVA?

Just curious what people think...

That stupid boolean type; C (and C++) had it all fixed: 0 or 0.0 or null is considered false while all the rest is considered true; it also allows for more obfuscated code but that James Gosling sissie probably couldn't read real manly man code ...

kind regards,

The uneducated public's opinion about it. "Oh you're using Java to program a game, isn't that slower than flash?"
Or the lack of any official general enthusiasm for game programming with Java, which goes hand in hand with public opinion. People think Java is for boring GUIs, and Oracle doesn't do much to correct that stigma.

What he said... The overall lack of support for Game Developers from Orcale is definitely my least favorite thing. As well as the assumption that Java is bad for game programming. AND the stuttering that I think is caused by drawing with Java2D (anyone else have this problem?)

What stuttering? Sounds like you're doing something wrong, to be honest.

Java is a great platform for game development, but the public doesn't realize it because there are only a few people who know how to do it right and then 99% of other people doing it wrong, giving Java a bad rep. "I always thought that Java GUIs were slow and unresponsive." No, that just means whoever wrote the program you're thinking of didn't know enough to do the work off the EDT. "I thought that Java graphics flickered." No, that just means whoever wrote that program didn't know how to paint correctly.

There's a stigma attached to Java, and to applets, webstarts, and Jars, and the few people doing it right aren't enough to sway public opinion. That's frustrating, but that just makes it our responsibility to prove the public wrong.

There is just a slight stutter in the drawing. Maybe it has to do with the way I draw or my game loop.
I draw by extending a Canvas, calling setBufferStrategy(2) to double buffer, then getBufferStrategy() to get the strategy and then I call getDrawGraphics() on the strategy. I also have doWhile loops checking startegy.contentsRestored() and strategy.contentsLost() like this:

Java Code:

do
{
   do
   {
      Graphics2D g = (Graphics2D) strategy.getDrawGraphics();
      // Draw here
      g.dispose();
   }while(strategy.contentsRestored());

   strategy.show();
}while(strategy.contentsLost());

And my game loop is fairly simple:

Java Code:

long start = System.nanoTime(), curr;

while(running)
{
	if(!paused)
	{
		updateGame();
		paintGame();
	}

	while((curr = System.nanoTime() - start) < period)
		try
		{
			Thread.sleep(1);
		}catch(Exception e)
		{}

	start = System.nanoTime();
}
System.exit(0);

EDIT: I am a noob game and java dev if that explains any of my programming flaws >_>
