It was considered at one point, but the main proponent for one JVM language has left the company and even before that there was strong support for keeping Scala on the list of production languages.

> the main proponent for one JVM language

Hey, I'm interested in that! What proponent? What language? If it was Raffi Krikorian would you mind having a look at https://en.wikipedia.org/wiki/Scala_%28programming_language%... and perhaps update it?

I was not a first party to the discussion, but what I heard is that Alex Roetter had asked the most senior engineers to consider strongly whether or not it would be better to have one JVM language. Twitter pays a polyglot tax and Scala's tool chain is clearly not as mature as Java's. In the resulting discussion, though, even engineers that primarily wrote systems in Java wanted to keep Scala as an option.

I had one conversation 5 years ago with Raffi about which language something should be built in. He advocated strongly for me doing it in whatever I felt made the most sense. I think this is typical of his management style -- which is to establish goals and let the people responsible for achieving those goals work out how to do it. Raffi had left the company by the time the JVM standardization discussion happened.

Thanks!

That would be news to me and I work there.

Any source ? Any idea why?

I work at Twitter.

No, we're not. Probably just some rumor.

I think he may be confused with LinkedIn
