other big things are java.utilconcurrent package and annotations, they will change the ways you write Java code. After Java 5,you suppose never use new Thread(), never use wait()/notify(), and the annotation is a whole new thing. JVM management and monitoring give you much more capabilities to monitor your program at run time.
