 Known not to work:
 
-* Java Debug Server. This doesn't work (yet) because it runs as a jdt.ls plugin.
-  Support for this may be added in conjunction with [ycmd][], but this

+* Java Debug Server. The [java debug server][java-debug-server] runs as a

+  of sense if you already happen to be running the language server. 
+  Vimspector is not in the business of running language servers. So, rather
+  than doing so, vimspector simply allows you to start the java debug server
+  manually (however you might do so) and you can tell vimspector the port
+  on which it is listening. See [this issue](https://github.com/puremourning/vimspector/issues/3)
