Warning: java 1.5 needed

Unfortunately I used a method from Java 1.5 in the current alpha. So you need the newest Java JRE from the sun website. I was going to release a 1.4 version of the lib this weekend. But I am using to many of the features of 1.5 already and am goin to use more and more of it, because Java 1.5 is a great improvement over 1.4. Sorry for any inconvenince this may cause
