Is it fashionable to bash java ? What about https://github.com/graalvm/truffle or https://bitbucket.org/allr/fastr/wiki/Home or https://www.youtube.com/watch?v=OUo3BFMwQFo ? There is serious innovation happening in java land (through Oracle - without talking about Clojure, etc.) Java EE exists because of the need to support large legacy, enterprise customers. For those who are starting out in Java web frameworks, peo…
Amen. Be it Hacker News, or the /r/java subreddit, or wherever, it feels like the bulk of Java chatter revolves around... 1. Security vulnerabilities 2. The Ask.com toolbar 3. Oracle abandoning Java EE ... which is extremely frustrating because... 1. Virtually all of the "security vulnerabilities" deal with the browser plugin for using applets, which hasn't been widely used in 15 years 2. The toolbar malware, while s…
I wonder how difficult it would be to port C# to the jvm. It really is a better language. There are some parts of the standard library that are better in java, but overall I'd say C# is better there too.

What are actual Java's shortcomings?
Mostly OOP's shortcomings. c2 wiki will lead you to much discussion on how "design patterns" are a band-aid patch for the deep, deep problems with massive OOP projects.
I don't think there is a problem with the Java Language or the JVM.
What are the current best bets for writing web apps in Java? Play! is convenient, but how does it compare to Spring Boot?
As well as those 2, Dropwizard is excellent if you're writing REST apis and provides many enterprise-friendly features out of the box.
SparkJava (don't confuse with Apache Spark) is a very lightweight Sinatra/Flask-like framework using Java 8 features, and good for REST apis too.
2 more to consider IMHO: Vert.x, and Comsat from Parallel Universe. Parallel Universe have one of the most interesting technologies in Java-land IMO. They provide a library called Quasar that adds suspendable green threads (similar to Erlang processes) to your code using bytecode instrumentation. This allows a single server to handled a huge number (think 00,000s) of concurrent connections. Vert.x has support for Quasar too.
I'm sure others have favourites too.

But the Java ecosystem is awesome. The language is great, the JVM is great. As long as you know what you are doing.

I've worked on the Microsoft stack for most of my career, and I'm curious what Java has/does that the .NET stack doesn't. Or is that more about the .NET core stuff for running on Linux-based systems?

Java EE is basically the official java server-side container. It was designed to scale, it kind of forced a designed pattern (something called 'Enterprise Beans' - one bean for dealing with requests, stateful beans for dealing with sessions etc.) It got huge and bloated. Some people came along and created some lighter frameworks. Arguably - Node.js - the javascript container is the real extension of this: it's incred…
Does Java have an equivalent to the Promise system in Javascript? I find it much more usable than callbacks for async-heavy applications.
There's also, in true Java tradition, a number of competing implementations of Promise based frameworks. The one I've used, Ratpack, defines and uses promises almost identically to JavaScript/Node.js.

Oh, by all the possible deities, how I wish that was even remotely true...

Except for the above malware comments, what exactly does "Install Java" mean? You cannot redistribute the installer or the installed files. Except other things it means, you cannot make a docker image with java app and redistribute it. Everyone has to download their own java installer and build images themselves.
I have no recriminations prepared for you but I am curious; where did you get the idea you can't make docker images for java apps? Did you piece it together mistakenly based on incomplete knowledge or is someone actually spreading that around?
