I am not in the mood to defend Java, but I would like to give a tip to people who keep mentioning J2EE: J2EE is from a bygone era; learn to say Java EE 6, which is better (although JPA 2 is really the only part I like) and take J2EE out of your vocabularies. Discussing J2EE kind-of makes it sound like your knowledge is out of date.

Also, Scala and Clojure are wonderful languages so I don't understand some of the negative comments about them.
