What was the last Java version you used? There has been a huge momentum in adding new features lately, granted, it is slower than in C# (Java's top priority is backwards compatibility, so it does not have the luxury of shedding old stuff or changing them once they are in), but in the last couple of years it has improved tremendously. The JVM (especially in the garbage collection front) but also the language - half of an ML-style language is there (for example, ADTs and pattern matching), the other half is coming soon!
