Server crashed
I am using this server installed by AUR via a client named eglot in Emacs.
As you can see from the AUR, Java that this server runs on is packed in the package, and its version is shown as follows:
openjdk 13.0.2 2020-01-14
OpenJDK Runtime Environment (build 13.0.2+8)
OpenJDK 64-Bit Server VM (build 13.0.2+8, mixed mode)
Then, I tried to launch the server via eglot, and eglot send following messages to this server resulting in an exception thown:
(:jsonrpc "2.0" :id 1 :method "initialize" :params
