Looks like you're also using lspconfig.jdtls.setup which creates the second client

No, lspconfig.jdtls.setup is comment out.

Please, I closed this issue by mistake. :S

[mfussenegger]

Well, It must come from something in your configuration or some other plugin

[arthureggert]

@realtica not sure if you solved this already or not. But I had the same issue this morning and I was able to solve it. The thing is, I'm using LazyVim, and it was automatically calling the lspconfig.jdtls.setup for all the mason installed LSPs.

What I did to disable it was on my file plugins\lspconfig.lua

return {
  "neovim/nvim-lspconfig",
  opts = {
    setup = {
      jdtls = function(_, _)
        -- this will disable LazyVim from setting up jdtls automatically
        return true
      end,
    },
  },
}

With this config the only JDLTS attached is the one that I create with require("jdtls").start_or_attach(config)
