Your Java language server is broken, how do you install it? Are you using coc-java?

Check https://github.com/neoclide/coc.nvim/wiki/Debug-language-server to get more info from language server.

Yes, I'm using coc-java, I finally found if we change to java 11, it's works fine, if change back to java 8, it breaks, but our project is base on java 8 so I hope someone could fix this bug if possible. Thank you.

删掉 CocConfig 中对应的文件, 例如
"directory": ".ccls-cache" 删掉 .ccls-cache 文件重新打开
