Go to definition opens file too slow

[cheonhyangzhang]

Use command gy can go to the definition of a Java class. I found it takes significant long time to open the file. E.g. when open java.util.Enumeration it takes about 30 seconds to open the file, during the time, the file is displayed but it's frozen, cursor won't move. This file is not having any too line lines which is a known issue for VIM. Not sure what is causing it to be open so slow. Do you guys have any idea or do you face similar issue?

I had this issue but it resolved after upgrading to the most recent version of vim/coc.

Hi @josuf107 Thanks for you response. Which version of vim-coc are you using?

[chemzqm]

Should be fixed on coc.nvim.

Try minimal vimrc if the issue still exists.
