I used Java years ago for Android dev, but stopped when I stopped doing that. Every once in a while I'll get the itch to work on a new project, and always wonder if Java would be a good idea.

My hesitance is that I don't trust Oracle (and don't know to what extent they're involved nowadays), I'm not familiar enough with the ecosystem to know what is legacy crap to avoid, and I think it's generally seen as an uncool language, and I'm way too cool to be taking such risks.
