Why? Deploying an application with Java is very easy and you can have intense monitoring built in with out having to use a third party like NewRelic (even though NewRelic adds a lot).
Java is always a mess to debug/troubleshoot. It eats memory worse than a bloated browser, and is slooooooow. I personally avoid projects that require java if I can help it.
I'm going to have to flat out disagree with you. I hear this all the time from java devs, but have never seen it in real life. Every implementation I've personally seen of java is extremely slow, and has horrible debugging utilities.
Ok. I'm going to have to disagree since I've seen it in real life several times. Also many large distributed system projects, such as Cassandra, Elasticsearch, Hadoop, etc. are all written in Java.
I guess we'll just have to disagree due to differing experiences. How does a language being used in different distributed system projects mean it's fast? It's just the language they chose to go with. That decision could have nothing to do with speed.
Ah yes, let's judge a project based on its implementation language. Because every Java program is insecure by default, and no exploits exist for anything written in C. Sigh.
