When last I tried it, maybe around 2014? I found it a kinder, cleaner Java with better tooling. Visual Studio (not Code) is still the best IDE I've ever used.

Unfortunately it's not popular in the circles I hang around in and the places I've worked. Now that .NET core is the one true runtime I'd welcome an opportunity to try it again; alas, I doubt I'll have such an opportunity (at least not through work).

I remember the upsides but I'm sure there are downsides I'm not aware of. I'd love to read a critique from someone with real world experience.
