What second second programming language should a java developer try?

Question

IT education

Recently, I realized that it gets boring to work on java on the back and js on the front - I would like to learn a second programming language that will work on jvm and use it in web development. What would you recommend to learn as a second language after java?
High remuneration and demand in the IT market is important. I ask you to justify this or that choice. Thank you!

Are you using kotlin in web development? How are you?
