Eclipse.jdt.ls version

1.33.0

Steps to Reproduce

Opening a multi module maven project at the root (in this case https://github.com/JanssenProject/jans), I open a Java file and get this exception on the nvim console:

Cannot invoke
Error executing vim.schedule lua callback: ...si/.local/share/nvim/lazy/nvim-jdtls/lua/jdtls/setup.lua:13: Vim(echo):E121: Undefined variable: org
stack traceback:
        [C]: in function 'nvim_command'
        ...si/.local/share/nvim/lazy/nvim-jdtls/lua/jdtls/setup.lua:13: in function 'handler'
        /usr/share/nvim/runtime/lua/vim/lsp.lua:1056: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

Expected Result

JDTLS should start normally

Actual Result

After hitting Enter, jdtls proceeds as normal and starts properly. This bug does not cause any other side effects.

The error appears to be coming from the status notifications but I can't reproduce is.

As a workaround you could simply mute the notifications:

config.handlers['language/status'] = function() end
