How to stop JDTLS quitting ("Exit code 13 and signal 0") every time I open a java file in neovim?

Question

I am fairly new to using neovim and set things up with kickstart.nvim. I tried to setup jdtls to run with mason. It was working fine until today, when it has been quitting immediately upon opening of a java file with the message "Exit code 13 and signal 0".

Here's were I've got to with my mason stuff (please see my full init.lua and config for context):

      local servers = {
        lua_ls = {
          settings = {
            Lua = {
              runtime = { version = 'LuaJIT' },
              workspace = {
                checkThirdParty = false,
                library = {
                  '${3rd}/luv/library',
                  unpack(vim.api.nvim_get_runtime_file('', true)),
                },
              },
              completion = {
                callSnippet = 'Replace',
              },
            },
          },
        },
        jdtls = {
          root_dir = vim.fs.dirname(vim.fs.find({ 'gradlew', '.git', 'mvnw' }, { upward = true })[1]),
        },
        angularls = {},
        html = {},
        ts_ls = {},
      }

      vim.list_extend(ensure_installed, {
        'stylua', -- Used to format Lua code
      })
      require('mason-tool-installer').setup { ensure_installed = ensure_installed }

      require('java').setup {}

      require('mason-lspconfig').setup {
        handlers = {
          function(server_name)
            local server = servers[server_name] or {}
            server.capabilities = vim.tbl_deep_extend('force', {}, capabilities, server.capabilities or {})
            require('lspconfig')[server_name].setup(server)
          end,
        },
        ensure_installed = ensure_installed,
        automatic_installation = true,
      }
    end,
  },

Here is the output in the lsp log file:

When I have had problems with it before it was usually because I needed to clean install my java project I'm working on but this is not the case this time. I've done that like 10 times.

Extra info: I'm using jenv and its running java version 21.0.3

I have tried every answer I've found on github, stackoverflow and reddit, including trying to just use nvim-jdtls with a ftplugin/java.lua file instead of my kickstart generated init.lua, deleting all the jdtls files in the mason folder and making it remake them etc. But nothing is helping.

I did see someone suggest clearing eclipse cache but I don't know where that exists or how to identify it.

I've been working on this for about 12 hours and I've tried a ridiculous amount of setups, please can someone explain what I'm doing wrong here?

I had the same issue. You have to update your Java to version >=21.
