I am a certified Java hater, but you’re allowed to like it. If simple and objected oriented is what you want, I can see the attraction, and it has a good and mature ecosystem.
The ecosystem is java’s biggest asset. C# is actually a pretty decent language to develop in but the ecosystem just pales. Zookeeper for example doesn’t have an official client. But one guy ported the Java client but it hasn’t been updated in years. Maybe it’s recently because I moved on from that job.
