//! Java harness emitter.
//!
//! Generates a Java `NyxHarness.java` that:
//! 1. Reads the payload from `NYX_PAYLOAD` / `NYX_PAYLOAD_B64` env vars.
//! 2. Calls `Entry.{entry_name}(payload)` from the co-located `Entry.java`.
//! 3. Catches all exceptions to prevent harness crashes from masking results.
//! Phase 14 (Track B Java vertical) replaces the single legacy `emit`
//! body with dispatch over [`JavaShape`] — the cross product of
//! [`EntryKind`] and a lightweight per-file shape detector that inspects
//! the entry file for servlet / Spring / Quarkus annotations, JUnit
//! markers, and `static main(String[])` signatures.
//!
//! Sink-reachability probe: fixtures explicitly emit `System.out.println("__NYX_SINK_HIT__")`
//! before the actual sink call (same pattern as Rust and Go fixtures).
//! Each shape emits a single `NyxHarness.java` that:
//! 1. Reads the payload from `NYX_PAYLOAD` / `NYX_PAYLOAD_B64`.
//! 2. Locates the entry class (default-package, derived from the entry
//! file basename) and invokes its method via the per-shape adapter.
//! 3. Catches all exceptions so the JVM exit shape stays observable.
//!
//! Build step: `prepare_java()` in `build_sandbox.rs` runs `javac NyxHarness.java Entry.java`
//! in the workdir. The compiled `.class` files land in the workdir.
//! Sink-reachability probe: fixtures explicitly emit
//! `System.out.println("__NYX_SINK_HIT__")` before the actual sink call
//! (same pattern as Rust and Go fixtures).
//!
//! File layout in workdir:
//! ```text
//! NyxHarness.java ← harness main class (generated)
//! Entry.java ← entry class (copied from project)
//! NyxHarness.class ← compiled by prepare_java()
//! Entry.class ← compiled by prepare_java()
//! ```
//! Build step: `prepare_java()` in `build_sandbox.rs` runs `javac` over
//! every `*.java` file in the workdir. Shape fixtures bundle their own
//! annotation / type stubs (e.g. a minimal `HttpServletRequest.java`
//! when the shape needs servlet plumbing) so the JDK can compile the
//! source without pulling Maven dependencies.
//!
//! Payload slot support:
//! - `PayloadSlot::Param(0)` — pass payload as `String` first argument.
//! - `PayloadSlot::EnvVar(name)` — set system property before calling entry.
//! - Other slots produce `UnsupportedReason::PayloadSlotUnsupported`.
//! - [`PayloadSlot::Param`] — pass payload as `String` first argument
//! (n-th positional for `Param(n)` where `n > 0`).
//! - [`PayloadSlot::EnvVar`] — set a system property before invocation.
//! - [`PayloadSlot::QueryParam`] / [`PayloadSlot::HttpBody`] — surfaced
//! to servlet / Spring / Quarkus adapters as the request body or
//! query parameter value.
//! - [`PayloadSlot::Argv`] — appended to a `String[] args` for
//! `static main` shapes.
//! - Other slots produce [`UnsupportedReason::PayloadSlotUnsupported`].
//!
//! Build container: `nyx-build-java:{toolchain_id}` (deferred; §19.1).
