class Analyzer::Java::Javalin

Overview

Javalin runs on the lambda-DSL routing style: app.get("/x", ctx -> ...) and path("/api", () -> { ... }) nested via app.routes(() -> { ... }). The shared TreeSitterJvmLambdaDslExtractor does the heavy lifting; this analyzer just supplies the Javalin method-name set and turns the raw scan results into Endpoints.

Javalin's request-context helpers. header and cookie double as response setters, but using them with a single string argument is overwhelmingly the read path — false positives here are cheap (a benign extra param to scan).

Instance-side view of the same declaration. The per-file rescues live on this base class, which has no way to name the analyzer that is running inside them, so a skipped file could not be attributed to a tech. Deriving it from analyzer_for keeps the name written exactly once.
