eglot-java-run-test fails with No applicable method: jsonrpc--request-continuations, nil

[skybert]

When I'm in a JUnit java file and have the point at a test method, running M-x eglot-java-run-test fails with:

cl-no-applicable-method: No applicable method: jsonrpc--request-continuations, nil

Expected:

Emacs runs the unit test with output in a compilation buffer.

Have the same problem.
Emacs version:
GNU Emacs 29.4 (build 2, x86_64-apple-darwin24.1.0, NS appkit-2575.20 Version 15.1.1 (Build 24B91)) of 2024-12-14
using the built-in Eglot version (~1.12).

With my very limited knowledge of lisp I've managed to track the problem to the function eglot-java--find-server:

  "Find the LSP server of type eglot-java-eclipse-jdt for the
current project. In the strange event that there are multiple,
return the first one."
  (when-let* ((project (project-current))
              (servers (gethash project eglot--servers-by-project)))
    (cl-find-if #'eglot-java-eclipse-jdt-p servers)))

The last line with cl-find-if always return nil (it never finds the server). If I change it to:
(cl-find-if #'eglot-lsp-server-p servers)))
it works although I don't understand why one works and the other no... :-\

Nice. I went down a different path: I wrote my own function (and removed eglot-java): https://gitlab.com/skybert/my-little-friends/-/commit/6caf437148157e3aa48074e861a22e4d2d884403
