What happened, and what did you expect?

JAX-RS allows @Path values without a leading slash, both on the class and on the method (@Path("widgets"), @Path("{id}")). The route extractor only accepts templates that start with /, so such resources produce no Route nodes and no HANDLES edges at all. In Java frameworks this spelling is common (JAX-RS spec, Jersey, RESTEasy, Quarkus samples).

A second, related gap: for Scala JAX-RS resources the class-level @Path prefix is not joined with the method path (it is for Java and Kotlin), so a Scala method route is emitted as the bare method template instead of <class path>/<method path>.

Expected: relative templates are accepted and normalized so the composed path is always rooted (/widgets/{id}), for Java, Kotlin and Scala alike.

Follow-up to #1005 (PR #1007 fixed class/method composition for rooted @Path values; templates without a leading slash are still rejected before composition runs).

Reproduction

1. Dummy snippet (Java):

@Path("widgets")
public class WidgetResource {
    @GET @Path("{id}")
    public Widget get(@PathParam("id") String id) { return null; }
}

Scala variant:

@Path("/widgets")
class WidgetResource {
  @GET @Path("{id}")
  def get(@PathParam("id") id: String): Widget = null
}

2. Command: codebase-memory-mcp cli index_repository '{"repo_path":"/tmp/repro"}' then
   codebase-memory-mcp cli search_graph '{"project":"repro","label":"Route"}'

3. Result: no Route node for the Java resource; for the Scala resource a Route with path {id}.
   Expected: Route /widgets/{id} with a HANDLES edge from WidgetResource.get in both cases.

Proposed fix

I have a two-commit fix with tests (relative-template acceptance + Scala class-level composition), rebased on current main:

Confirmations

• I searched existing issues and this is not a duplicate.
• My reproduction uses shareable code (a dummy snippet), not proprietary code.
